Precious Data in the Hands of Technology

Technology has jumped leaps and bounds in the last decade, and data has come of prime importance for corporates to work their magic, but they still need the magical wand to accomplish this. Well they have got it, web hosts from around the world are in a frenzy to deliver state of the art infrastructure for SMB’s and large scale industries to host their data, and this has come in the form of VPS and cloud hosting.

Well, everybody’s heard of computers, hard-drives, etc. to store and execute data and run different programs on it, storing data on the web comes with the basics of VPS that involve the technique of virtualisation that means dividing a single server into multiple servers. Virtual servers host data with other data that is saved on other partitions of the server. In this kind of hosting, resources are shared with data of other clients on that server. This kind of server technology is good for businesses that do not have a lot of data or high spikes in traffic.

VPS servers are the easiest and cheapest way to host data on the web, hosting on VPS renders clients to upload their data, track visitor stats, create new accounts, and work with their personal information like username, passwords, so o and so forth. Clients looking out for Linux or Windows VPS should look at the amount of storage, bandwidth, control over data and personal information, systems support for scripts and databases, ability to install applications seamlessly, create email accounts and much more.

The next step of virtualisation is cloud computing, this technology delivers shared resources to clients on-demand, cloud servers and VPS deliver flexibility, performance, saves capital cost, and much more. Hosting data on the cloud is the modern wave of virtualisation technology as it renders full virtualisation, state of the art management, optimisation of resources, and enhanced automation.

Virtual Private Servers deliver single and independent solutions at lower costs to smaller companies, the cloud VPS also called as Infrastructure-as-a-service deliver managed infrastructure in the form of virtual instances, these components can include capacity, storage, RAM, Processing Power and lots more, clients are given the option to select their own operating system like Windows and Linux, a virtual private cloud or virtual private data center is virtually partitioned from a large cloud setup through a VLAN and is maintained by service providers.

A virtual private cloud is said to be an amalgamation of cloud computing with a virtual private network in place. A virtual private cloud is derived from interconnecting cloud resources with enterprise sites and VPN’s. Therefore cloud computing or cloud hosting is the new wave of the future by providing flexible and on-demand resources, global clients are using this technology seamlessly across various platforms and will continue to do so in the future. This is where cloud hosts are working day in and day out to deliver state of the art services to clients all around the world.

In those days, especially in the software industry there was limited number of technologies. Java, C++ were common in those days. Situations are different nowadays. Chronologically, many new technologies came into existence. These include Ruby, Python, Objective C. Learning a few computer languages does not make one ready for the job market, unless one acquires some extra skills.

Mobile

In recent times, mobile or smartphone has become an indispensable part of an individual. It is used for communication. Nowadays, the businesses across the world, develop websites which are mobile friendly. With the increase in popularity of IOS and Android based mobile phones, companies across the world seek the services of professionals who are expert in app development. Research reveals that employers of corporate firms tend to hire professionals who have adequate exposure in mobile app development.

Big data

IT companies work with big data. They collect huge amount of data for that purpose. When it comes to managing or organizing the data then they find it really difficult to do so. One of the hot trends in the software development industry, from the employer’s perspective is the requirement of data analyst, data scientist, computer system analyst. Those who are directly associated with the IT industry, for them, working with data becomes prerequisite.

Cloud

Often we as computer or mobile internet users tend to save important documents in the storage devices including the cloud storage device. The advantage of using cloud storage to save data is that one can safely choose to fire other hardware where the same data has been stored. The cloud technology introduces the need to hire data scientist and cloud security professionals. The mobile devices along with the cloud technology allows us to seamlessly access data, either for personal use or for professional purposes. With the proliferation of cloud technology there is an increase in the demand for workers who are skilled in cloud computing, cloud security.

The Features and Benefits of Laptop Computers

When we look around at all the people on their laptops typing away or simply using them to listen to music while we read we may find ourselves amazed at the technological revolution that is upon us. The days of mainframe computers are behind us and the day of mobile cloud computing is here. The laptop is the backbone of the new modern age.

There are so benefits of laptop computers that make them essential in this modern age. Some of those are, but are not limited too, syncing data to the cloud so that it is available anywhere and everywhere, the ability to access the all of the knowledge and information of the internet anyway and everywhere, and having a full service entertainment center capable of player mp3s, CDs, DVDs, Blu-rays, and the countless streaming movies and music sites. The availability of the information of the internet is available because of recent advances in the area of mobile broadband internet. What was pioneered in the cell phone industry has made its way to laptops and cemented itself as a must have for people who use their laptops on the go.

Syncing your information to your home computer, work computer, laptop, and the cloud is by far the best thing about the modern era of laptops. This means that if you are surfing the internet on one computer, then go home and want to be at the exact same page then you can do that. Also, you can use free software and websites such as Dropbox, SugarSync, Windows Live Mesh, and many others to have your data backed up to the web, which in this type of situation is also called “the cloud”, and have it synced across all of your computers at the same time. Another benefit to these types of sites is they make sharing information with team or family members incredibly easy.

Being able to access the internet and feed your media fancy anywhere are the next two best things about laptops. Both of these features can be used while in areas with WiFi, a wireless networking signal provided by the location you are at, or be accessed by the use of a mobile broadband card. These cards can come built in to the computer or be purchased later and added internally or externally via a USB connection.

Laptops have freed people from the desk and allowed the information of the world to be at your finger tips no matter where you are in the world.

Online Database – Key Advantages And Disadvantages

Database in a business scenario is commonly associated with a list of leads or customer information, though in a more technical environment it can also be referred to as Microsoft SQL Server, Oracle or Sybase. Traditionally available offline, databases have also spread across the online horizon delivered over the internet and available on a monthly subscription basis. Though Wikipedia gives you a wide list of online databases, here I’ll mention only about the advantage and disadvantage of getting your data online and forming an online database of your own.

Since the past ten years we have been collecting data using spreadsheets and enhancing our skills to convert it into a database which comes in handy later. Microsoft Access, SQL and Oracle has come along a long way supporting spreadsheets as the complexity of the database increased and it started falling apart. But these databases were available only on a single desktop or accessed over a LAN connection to an in-house server. Easily tackling the desktop spreadsheet applications in the mid-field, web-databases are closing in to score and has become the lifeline of people moving their data online. Most of these web-databases are hosted in a Cloud environment and protected by SSL encryption and a secure log-in with proper User Access Control.

Some advantages of using an Online Database

Online – As the name suggests, an online database can be accessed from a web browser from anywhere in the world. With Cloud Computing coming to the foreground, it is much easier to host an online database in an elastic public cloud making it more scalable and secure.

Elasticity – A web-based-database can hold infinite data and is totally elastic in nature. Whenever there is a surge in data flow, more storage space can be allocated and scaled up and down based on requirement.

Multi-tenancy – A public cloud database is generally multi-tenant in nature. This means the same database can be used by multiple customers on a shared model where you pay only for the space you use.

Pay-Per-Use – Monthly subscription based pay-per-use model makes online databases look quite lucrative where you do not need to invest a huge Cap-Ex on licensed software.

Limitations or disadvantages of an Online Database

Security – One of the gravest concerns of using a web-database is security. With not many security standards available in the Cloud Computing model, most of the users are worried about putting their financial data online.

Switching – Another concern when selecting an online database is switching. Different databases support different formats and switching from one to another becomes a pain thereby increasing switching cost.

Downtime – There are times when the server can be down because of multiple reasons which can lead to huge data loss and inaccessibility thereby causing great losses to customers.

Online database can improve your productivity in many ways and can serve multiple functions. You can customize an online database according to your business workflow or simply use it for data collection and information sharing. Web-based-databases work on different environments, so that is the biggest advantage you can get.

Turn a Physical Linux or Windows Machine Into A Virtual Machine for Free

We will be focusing on creating this masterpiece in the Windows environment, but don’t worry the same principles can be used in any operating system that can run Virtual Box.

List of Software and Hardware needed:

Software:

-Virtual Box and Extension Pack

-Windows 7 or higher PC or most any Linux Distro

-Redo Backup and Recovery ISO

-YUMI installer

Hardware:

-USB flash drive

-USB hard drive

The overall benefits of performing this procedure is three fold. One, cost savings on power, climate control and space required will be seen instantly. Two, manageability and scalability dramatically increases due to working with virtual disks and virtual networks that can scaled up or down with finer grained control. Three, redundancy and faster disaster recovery that is provided by cloud services. Especially when tied into your already existing network infrastructure for a seamless transition when disaster strikes.

While this process can be completed in numerous ways with different software, this is the way that I am familiar with and all the tools needed are free.

Sounds daunting? No sweat, but where do we start first?

Well, we need to get an image of the physical machine onto removable media (USB hard drive). I recommend a USB hard drive vs. just a USB flash drive due to the space the image will take up. We will also need a USB flash drive at least 2 GB in size to use as a bootable media for Redo Backup and Recovery.

Plug the USB hard drive into your USB port and open up the folder structure. Create a folder in a location that you can remember I.e D:”Your Computer’s Name”. This is the location where we will install the files from our initial physical image copy to. After this is complete, eject your USB hard drive by right clicking on the “Safely Remove Hardware” icon in your taskbar and click on Eject “whatever your USB hard drive is named”, unplug the USB HDD.

Next, we need to create a bootable USB to load Redo Backup and Recovery on. Download a small program called “YUMI”. YUMI will create a bootable USB flash drive for Redo Backup and Recovery on it. Also grab a copy of Redo Backup and Recovery, save both files to your desktop or location of choice.

Now, run YUMI and choose your USB flash drive from the list (Remember to choose your USB drive and not your USB HDD that should be unplugged anyway!). Choose “Redo Backup and Recovery” from the software list that you can create an installer for. Click the “Browse” button to look for the Redo Backup and Recovery.iso to include on the install. Finally click on “create” to start the bootable Redo Backup and Recovery bootable USB creation process. When this is done, YUMI will ask you if you want to add any more distros, just say “no”. Eject your USB out of the computer using the “Safely Remove Hardware” icon in your taskbar and click on Eject “whatever your USB flash drive is named” and unplug the USB flash drive. Please keep Redo Backup and Recovery.iso we will need it later.

Make sure that the physical computer that you would like to virtualize is in a powered down state, if not please power down the computer. Insert only the USB flash drive into the computer. Power up the computer and press the correct key to access to boot menu or make sure that the USB drive is set to boot before the computers internal hard drive. Choose the USB entry to boot from, YUMI should now load. Choose the entry for “Tools” then “Redo Backup and Recovery”. Press enter on the Redo menu to start the mini recovery O/S. When Redo Backup and Recovery is loaded, insert your USB HDD and give it about 20 seconds.

Open Redo Backup and Recovery Software:

1. Choose “Backup”

2. Choose your disk to backup (your physical computer’s disk)

3. Choose your partitions to backup (typically it would be all partitions and MBR)

4. On the “Destination Drive” screen choose “Connected directly to my computer” and click browse.

5. Locate the file folder we made earlier I.e D:”Your Computer’s Name” click OK.

6. Choose a name for the disk image. I will usually choose the date, click next. The backup process will take anywhere from 1 hr to 3 hrs depending on hard drive capacity and computer speed.

Congratulations, at this point you have made a full backup of your physical machine. Please click “Close” on the Redo and Recovery Backup program and choose the power button in the bottom right corner of your screen. Select “Shutdown” and let the computer shutdown. Remove both USB flash drive and USB HDD and boot up any computer that has Windows 7 or higher installed on it.

Now, lets turn that physical machine into a virtual machine!

Open up Virtual Box and choose “New”. Give your Virtual Machine a name and choose the type of virtual machine it will be as well as the version. Choose your memory size, I usually a lot 2 GB=2048 MB if I plan on running it on a machine that has 4 GB of ram physically installed. Create a new hard drive, choose VHD as the hard drive file type, click next. Choose “Dynamically allocated” for the storage, click next. Give your VHD hard drive a name, I will usually name it by whats running on it, hence name it what you named your computer. Make the VHD hard drive large enough to store your operating system, I will usually choose 200GB to be on the safe side. Again this depends on how big your physical machine’s data was. You are now returned to the Virtual Box Manager screen with your new VM present. Make sure your Virtual Box extension has been installed. Obtain the extension for your software version and install it like so:

In Virtual Box, click File–>Preferences–>Extensions–>Add Package–>Locate extension file and select it. It will be automatically installed.

Prepare the conversion! Use only Option A or Option B:

Option A: If you can get USB support working in Virtual Box:

Make sure that you have installed the extension pack and setup USB access properly, if you are having some troubles, refer to the Virtual Box document here:

https://www.virtualbox.org/manual/ch03.html#idp55342960

In Virtual Box, click on your VM name and choose “Settings” at the top, choose “Storage”. Click on the empty CD/DVD icon and then the CD/DVD icon on the right under “Attributes” and select your Redo Backup and Recovery ISO and click “OK”. At this point you have the Redo Backup and Recovery.iso at the ready and a blank VHD to install to. All you need to do now is insert your USB hard drive and skip over Option B because you do not need to perform it.

Option B: If you cannot get USB support to work in Virtual Box. No problem, its what happened to me so I found a way around it.

In Virtual Box, click on your VM name and choose “Settings” at the top, choose “Storage”, choose “Add hard disk” next to Controller:Sata or Controller:IDE whatever you have. Choose “Create new disk”, choose VHD and again make it 200GB Dynamically allocated and name it “Installer”. Underneath “Storage Tree” click on the empty CD/DVD icon and then the CD/DVD icon on the right under “Attributes” and select your Redo Backup and Recovery ISO and click “OK”. At this point you have the Redo Backup and Recovery.iso at the ready and a blank VHD which is named after your computer and another black VHD named Installer. Now close Virtual Box and right click on “Computer” and choose “Manage”. Left click on “Disk Management” then right click on “Disk Management” again and choose “Attach VHD”. Browse for the location of your Installer VHD that you created in Virtual Box, usually in the “My Documents” folder and click okay. Now you can copy the physical computer backup image that we took earlier from D:”Your Computer’s Name” to Installer VHD. After the contents have been copied, right click on computer management again and click on “Detach VHD”. Open up Virtual Box and proceed to the next step.

Lets Convert This Thing!

Once you have either USB support or the Installer VHD setup and the Redo Backup and Recovery ISO mounted. Press “Start” on your VM name in Virtual Box. You will be met the familiar Redo Backup and Recovery boot menu, press enter to proceed. Launch the Backup and Recovery program if it did not start automatically. Choose “Restore”. In a nutshell, you will choose where your Image backup is “The Source Drive” (your USB HDD or Installer VHD if applicable) and where to install the image (blank VHD named after your computer). After you have chosen to install into the blank VHD, confirm the prompt to overite any data and let the recovery process begin. After this is finished, click close and shutdown Backup and Recovery as you did before. The VM should stop running. Click on “Settings” from the Virtual Box Manager and unmount the Backup and Recovery ISO and the Installer VHD if applicable. Leave your VHD with the name of your computer or whatever you named it and click on “OK” to go back to the Virtual Box Manager. Click on “Start”, you should now be looking at a fully virtualized version of your physical computer!

Celebrate the many uses of this power little VHD!

You can transport this VHD and include it in any Virtual Box VM instance or even VMware if you are so inclined. You can run it on your local premises or deploy it in the cloud. A cloud instance of this VM would either require running Virtual Box on your cloud computing instance, or running it natively in your cloud computing space if the hosting provider supports it.

Common Gotchas and Troubleshooting:

Q: When trying to run my Linux based virtual machine, I get ” not syncing: VFS: Unable to mount root fs on unknown-block(0,0) “?

A: This is because in the backup and recovery process all the entries for hda##, hdb## and so forth have been converted to sda## extc. First, copy your precious VHD so you won’t lose your work if something goes wrong. Then all you will have to do is mount Backup and Recovery ISO, start your VM again and bring up a terminal session. Mount the Root partition and edit the entries in GRUB or Lilo to the proper boot device. For example: in GRUB, the entries are included in menu.Ist and fstab. In Lilo they are included in /etc/lilo.config and then /sbin/lilo -v to write the changes.

Q: When trying to run my Windows based virtual machine I get a boot error?

A: Obtain a copy or a Windows disc and mount it inside of Virtual Box making sure it is set to boot first. Choose the “Repair” option. Choose “Start Up Repair” and let it run. If this does not do the trick, go back into the “Repair” option and choose “Command Prompt”. Try these commands one at a time, shutting down and unmounting the Windows disc each time to check if the problem has been corrected:

bootrec.exe /FixMbr. Then restart to see if resolved. If no result, try:

bootrec.exe /FixBoot. Then restart to see if resolved. If no result, try:

bootrec.exe /RebuildBcd. Then restart to see if resolved. If no result, try:

You may have to remove your BCD folder by running these commands one line at a time without quotes:

“bcdedit /export C:BCD_Backup

c: <—- Only if your Windows installation is installed on C:

cd boot

attrib bcd -s -h -r

ren c:bootbcd bcd.old

bootrec /RebuildBcd”

The Future of Backup and Recovery

There has been an expanding growth in the need for provision of security features for data, especially now that data is getting stored and shared on the cloud. This market is growing tremendously providing services to the data archiving segment which includes companies who store a great deal of sensitive and confidential information on their computer systems. The need for protecting such data is vital and must not be lost or accessed by data thieves and hackers. Malicious use of company data can cause companies to suffer devastating losses in financial terms, reputation, and so many other facets of doing business. The question then becomes: why retain such a massive volume of information whereas it would be easier to do away with the information (managing all the data invokes cost implications). However, companies have to comply with international standards of conduct which may demand that data is kept at least for a prescribed duration of time. This is where the need for backup and recovery services comes in: technological advancements make it easier to manage loads of data that is stored and protected for increasingly longer durations.

Therefore, backup and recovery services have become an absolute necessity when it comes to the management of data. While many people would naturally want to avoid the likelihood of having data get lost or corrupted, they tend to underestimate the possibility of it happening. Backup and recovery is the most efficient way to approach data management, certainly preferable to spending valuable time and resources to try and recover lost data manually. Proactive backup and recovery services are provided at a small annual cost that is definitely unrivaled by what a company or individual may have to incur finding a means to reconstruct and recover data that has already been lost or corrupted. There are 3 major backup and recovery options: 1) offline backup, in which the process to transfer data to a totally different location other than the network used is both effortful and time-consuming; 2) online backup which is often directly synced to the company’s network, allows for fast and easy access to data, and recent additions are backed up consistently; and 3) the near line backup, which is a combination of offline and online data backup and recovery. It is less expensive but slower than online backup.

Moving away from the traditional, agent-based types of backup and recovery, the continued growth in backup and recovery needs suggests that the future of backup and recovery should address many issues, including data on the cloud. There has been great news filtering in regards to the cloud backups. This is perhaps the most important part of the ongoing discussion concerning the future of backup and recovery since the trend in the world today involves virtualization of many aspects of data storage. Propositions for features that future backup and recovery should provide are numerous. With virtualization of many operations on servers and desktops, backups will be required to be hypervisors, constantly aware of the data and environment to be supported and duplicated. This in effect will go towards the backing up environments such as the VMware, HyperV and the XenServer just as they are and never as if they were physical servers. Companies and organizations will require the ability to administer, stipulate, monitor, and protect critical applications irrespective of whether within the cloud, physical servers, virtual machines, and any combinations used.

Future backup and recovery has been envisioned to provide a user interface that is able to simplify application of the service but at the same time achieve a complexity of task. Future backup and recovery must avail all applications to the user, and provide auto discovery of tasks and their interdependency. Applications will need to be sorted out depending on which are more critical. Some tasks are often labeled mission-critical, while others are business critical among other levels. The continued movement towards cloud services sees the need for an all-inclusive backup technology that will achieve full recovery of features and data from the computer, as well as Smartphones and tablets which are now present in businesses.

In addition, cloud computing requires backups that address the multi-tenant environment which includes the physical servers and the virtual servers. The requirement for definitive recovery time objectives and recovery point objectives should also be incorporated for cloud backups. The other feature that future backup and recovery should have is the ability to backup and recover data from various online cloud platforms and even emails. Lastly, B&R plans should offer assurance for all involved in these processes from the system administrators to company executives and owners. Future data recovery plans should even suggest the best method to go about securing data. The options available would range from the typical backups to disks, cloud backup, application specific protection, the use of snapshots, synchronous and asynchronous replications of data, and continuous data application. Such features will provide monitoring of hardware failure and problems of the operating system and application layers. Such a tool would be useful for critical systems and applications DR, local recovery, computer backup for company networks and systems, and lastly, the remote backup and recovery of office data.

There has been continuous research and development regarding future backup and recovery plans that will be launched, as well as the scope to which data backup and recovery will be enhanced commensurate with trends in the IT world, specifically those concerned with data.

The Convenience of Modern Technology

When you are operating a business, regardless of whether that business is large or small, you are going to need to depend upon various types of technology in order to make sure that it runs smoothly. The exact type of technology that is going to be necessary in order to operate the business will differ depending upon the specifics of what the business needs as well as the size of the company. Although there are almost endless variations of items that may be necessary, here are some that you are no doubt going to need to consider.

Computers have become a part of our everyday life, and this is true not only with our business but also in our home lives as well. They can certainly help to make our lives easier, and when used properly, they allow us to get a lot more work done during the day. The type of computer that you are going to need is going to be determined by several different factors. One of the things that you are going to need to consider is if it is necessary for you to have a server with various computers attached to it or if each computer within the company is going to operate independently. You should also consider if you should have a stationary PC or if you should use laptops to allow your employees to travel with their work.

A newer technology that is related to your use of the computer is known as cloud computing. With cloud computing, you access the information that is needed via a remote server instead of a local server. This has many different advantages, provided you choose a company that offers you the security that is necessary. One of the primary benefits is that it can help you with document control, as well as the fact that you can access the information from any computer regardless of where you happen to be.

Other technology is also going to be necessary, such as the business phone systems that may be needed. For some companies, the telephone is simply a way to contact other individuals, but there are times when it is also going to be beneficial for inter-office use. For example, some of the Nortel phone systems, as well as many of the other upgraded phone systems, not only have the standard telephone features that you may need but also have many upgraded features as well. For example, they may allow for conference calling, which is great for having everybody in on the meeting, even if they are not there physically.

As your business continues to grow and expand, you are likely to find many different items that are necessary as far as technology is concerned. Just keep in mind, there are always going to be options that are available that will help to make these technological items more convenient and allow your company to operate smoothly. Just make sure that you take a little bit of time to look at the options that are available, and if necessary, ask someone with the knowledge to help you make a wise decision.

What Is Windows Azure and What Are Its Benefits?

Today large companies like Amazon, Google and Microsoft, that have extensive experience managing large data centers, are offering customers to “rent” data capacity. This is great news for companies that want to focus on their core business application and not worry about the underlying platform. Microsoft’s cloud platform offering is called Windows Azure.

Microsoft Azure, Microsoft’s premiere cloud platform, has contributed to significant revenue growth for Microsoft since its launch in 2010, coinciding with the company’s ongoing transition into the cloud market by forming strategic partnerships with cloud leaders like Salesforce.com. Not only does Azure boast strong platform-as-a-service (PaaS) capabilities, but the solution is currently the only major cloud platform that is a leader for infrastructure as a service (IaaS), as ranked by Gartner. Recently, Forbes predicted that annual revenue for Azure would be close to $2.3 billion.

Azure is gaining traction as the cloud infrastructure of choice for many IT professionals. Here are a few reasons these pros are turning to Azure as their cloud platform of choice-and perhaps why your organization should also consider doing so:

Cost Savings and Quick Scalability

With a model such as Windows Azure, companies only need to pay for the resources that their applications are using. Should a company need to increase its number of users or its data storage, for example, Microsoft can simply adjust their rate, making it extremely convenient and scalable. With this “pay-as-you-go” approach, businesses only pay for the amount of space that they need, instead of having to pay for empty storage at the maximum amount which they may never use.

Reliability

In addition to cost savings and quick scalability, another advantage of Windows Azure and the IaaS/PaaS model is reliability. Windows Azure services are provided from cloud data centers which have multiple built-in redundancies. If one server crashes, a company’s applications will automatically run on another server in the data center.

Easy Upgrades

Microsoft Azure supports many different programming languages, tools and frameworks, including both Microsoft-specific and third-party software and systems. New web applications and upgrades can easily be added.

Closely integrated with other Microsoft tools

For organizations that are reliant on Microsoft tools like SharePoint (which was recently ranked the No.1 platform for enterprise collaboration), Office 365 and Outlook, investing in a cloud platform that seamlessly integrates with Microsoft products makes sense. Organizations can also use the same virtual machines in Azure that they use on-premises, like Windows and Linux, which further simplifies operations. Many industry experts expect Azure to slowly but surely gain adoption due to this ability to offer users a completely seamless and integrated service package.

IaaS and PaaS

Azure boasts an enticing combination of IaaS (managed) and PaaS (unmanaged) services. IaaS enables companies to outsource their cloud computing infrastructure and pay for only for what they use. PaaS allows companies to create their own Web apps and/or software without having to buy and maintain the underlying infrastructure. This enables organizations to customize their cloud software-like Office 365, for example-to meet their exact specifications and requirements. Because Azure is an industry leader in both of these categories, companies can more quickly and easily build, deploy and manage applications.

Strong BI and analytics support

Azure provides managed SQL and NoSQL data services and built-in support for digging deeper into data and uncovering key insights for improving business processes and decision making. Specifically, organizations can leverage their SQL Server in the cloud and can use HDInsight, Microsoft Azure’s Apache Hadoop-based cloud service, to build Hadoop clusters to more deeply analyze data.

Azure has a fully integrated delivery pipeline

Once you start comparing Azure benefits from an enterprise perspective you realise that there are many elements beyond mere storage.

From an architecture perspective, you really need a unified delivery pipeline – here’s Azures:

  • Source control
  • Unit testing
  • Integration testing
  • Delivery
  • Go live tools

While the argument can be made that assigning specific workloads to different environments can at times be advantageous. There is great continuity and reduces risk of integration failure when all tools are available under one umbrella.

It means that in the case of product updates or any other changes, Azure can guarantee [to a high degree] that their pipeline is designed according – which creates a compelling business case.

Disaster recovery in Azure

With data being transferred globally, it is important for providers to have in-built fail-over and disaster recovery capabilities. They have regional and global fail-over options, hot and cold standby models as well as rolling reboot capabilities that work out of the box. These capabilities put them far beyond the, plain-old storage option. While this may not be something that is a daily issue to a business, it is definitely something that you can confidently know is happening in the background.

An Introduction To Cyber-Crime

Computer crime refers to criminal activity involving a computer. The computer may be used in the commission of a crime or it may be the target. Net-crime refers to criminal use of the Internet. Cyber-crimes are essentially a combination of these two elements and can be best defined as “Offences that are committed against individuals or groups of individuals with a criminal motive to intentionally harm the reputation of the victim or cause physical or mental harm to the victim directly or indirectly using modern telecommunication networks such as the Internet (Chat rooms, emails, notice boards and groups) and mobile phones (SMS/MMS)”. [1]

In its most simple form, cyber-crime can be defined as any illegal activity that uses a computer as its primary means of function. The U.S. Department of Justice broadens this definition to include any illegal activity that uses a computer for the storage of evidence. The term ‘cyber-crime’ can refer to offenses including criminal activity against data, infringement of content and copyright, fraud, unauthorized access, child pornography and cyber-stalking.

The United Nations Manual on the Prevention and Control of Computer Related Crime includes fraud, forgery and unauthorized access in its definition of cyber-crime. Cyber-crime in effect covers a wide range of attacks on individuals and organisations alike. These crimes may include anything from an individual’s emotional or financial state to a nation’s security.

There are two main categories that define the make up of cyber-crimes. Firstly those that target computer networks or devices such as viruses, malware, or denial of service attacks. The second category relate to crimes that are facilitated by computer networks or devices like cyber-stalking, fraud, identity-theft, extortion, phishing (spam) and theft of classified information.

In order to highlight the scale of cyber-crime globally, the Norton Cyber-crime Report 2011 revealed 431 million adults in 24 countries had been victims’ of cyber-crime in that year. Computer based crime is escalating at an alarming rate. In the report Norton calculated the financial cost of global cyber-crime at $388 billion. This is more than the combined international market for marijuana, heroin and cocaine, estimated at $288 billion. Assuming its current growth rate continues, cyber-crime will soon surpass the entire global drug trafficking market that is estimated to be worth $411 billion annually.

Cyber-crimes have expanded to include activities that cross international borders and can now be considered a global epidemic. The international legal system ensures cyber criminals are held accountable through the International Criminal Court. Law enforcement agencies are faced with unique challenges and the anonymity of the Internet only complicates the issues. There are problems with gathering evidence, cross-jurisdictional issues and miscommunication related to reporting.

It is widely known that victims of Internet crimes are often reluctant to report an offence to authorities. In some cases the individual or organization may not even be aware a crime has been committed. Even though facilities for reporting incidents of cyber-crime have improved in recent years many victims remain reluctant due essentially to embarrassment.

International cooperation is essential if an effective response is to be found against global cyber-crime. No nation can expect to effectively combat the issue alone. Many computer based crimes are initiated ‘off-shore’ and this presents enormous challenges to any nations law enforcement agencies. It is critical that agencies from around the world formulate actionable plans to detect, follow, arrest and prosecute cyber criminals.

For example, in the past two years Australia has adopted the National Criminal Intelligence Fusion Capability, a key element of the Commonwealth Organized Crime Strategic Framework (COCSF). This body brings together expertise, data and technology across a range of government and law enforcement agencies and enables international collaboration.

The problem of cyber-crime seems almost immeasurable in size. Looking at recent trends and advances in mobile technology and cloud computing we realize it is an ever-evolving and rapidly changing dynamic. There is growing evidence globally of newly formed partnerships between government and industry aimed at prevention. These partnerships create opportunities to share information and bolster law enforcement response to organized Internet-based crime.

This sharing of information creates concerns in its self. It is an extremely complex and sensitive issue. A balance must be found in efficiently maximizing distribution of information and protecting it from the organized cyber-criminal element.

Cyber-crime covers such a broad scope of criminal enterprise. The examples mentioned above are only a few of the thousands of variants of illegal activities commonly classed as cyber-crimes. Computers and the Internet have improved our lives in many ways, unfortunately criminals now make use of these technologies to the detriment of society.

Remote Patient Monitoring Using Mobile and Cloud Computing

INTRODUCTION

The Internet of Things (IoT) is the next paradigm shift, where sensors are connected to the Internet, which collect data for analysis to make our planet more instrumented, interconnected and intelligent. A typical person carries on average one or two mobile devices nowadays. Hence, by leveraging the increasing presence of mobile devices the cost of equipment can be reduced significantly in many industries.

A. Motivation

The ECG iOS application presented in this paper focuses on the health care domain of IoT. With the advancements in embedded information and communication technologies, we can provide intensified healthcare support of senior citizens at homes and retirement homes. This type of technology would be helpful to be providing ECG monitoring facility to senior citizens, athletes and common people. By providing the facility to use these technologies in the home, citizens would be able to live independently for a longer period of time, helping to reduce costs of medical equipment Healthcare is currently facing the challenge of large amount of data that is unstructured, diverse and growing at an exponential rate. Data is constantly streamed through sensors, monitors and instruments in real time that is faster than the medical personnel can keep up with. The advanced techniques and high capacities of cloud computing, processing of a large amount of data can be performed more efficiently support big data analytics.

B. Problem statement

In the healthcare domain of IoT, patients will not have to make as many trips to the doctor anymore, since they can upload the collected data from the sensors to the cloud. This can be achieved for an ECG monitoring application on the mobile device, which will collect the bio-signal data using sensors and then upload to the cloud for keeping a record of the unstructured data. This will reduce the waiting time for the triage at the hospitals and minimize visits and reducing the cost of personnel and administrative operations. This convenience increases the quality of life for the patients as they can enjoy other activities instead of spending time commuting to the hospital/clinic and waiting in long triage queues.

C. Proposed solution

In addition to medical knowledge, various SSE Technologies are involved in IoT based healthcare applications, including microcontroller and sensor technologies, signal processing, communication protocols, system and software design (using well documented design patterns), DBMS, web services, data analysis, and cloud techniques. Such an infrastructure should not only satisfy the basic functional requirements, but also address some key non-functional quality requirements, such as Performance, privacy/security, portability, scalability, flexibility, and cost. Using the idea of IoT and cloud techniques, this paper presents a solution to use an ADC and microcontroller board, which obtains the bio-signal data from a person using sensors and sends it to the mobile device wirelessly using Bluetooth technology. When monitoring the ECG of the patient, the monitored data associated with the ECG waves being displayed on the mobile app is stored in the form of a binary file on the secure digital (SD) card of the device and the user has the ability to upload it to a structured query language (SQL) Server private database. With the proper hardware components like the ADC and microcontroller and the sensors, the solution can monitor the ECG of a person in any environment at low costs, without having to purchase any costly ECG monitoring devices.

DESIGN AND IMPLEMENTATIO

A. Mobile-Based Healthcare Service:

Mobile devices are evolving at a rapid pace in the deployment of healthcare services. Our system is mainly based on real-time long-term health monitoring, catering to the demand of assisted living and health fitness information provider. Thus, the deployment of mobile devices into the mobile healthcare system focuses on several significant features for a medical healthcare system.

B. Communication between Mobile Device and Web Server:

Bluetooth data transmission is applied into the system because Bluetooth facilities are available in numerous smart devices, including portable tablet devices, laptops, personal computers, and even smart TVs. Conceptually; Bluetooth is a open wireless protocol operating in the 2.4-GHz band designed for a medium data rate that averages approximately 2 Mbps.

C. Web Server Cloud Healthcare Service:

Using a Web server healthcare cloud computing system, immediate access to the healthcare tracking system is possible anywhere. The ECG data are displayed in real time on the mobile device. To ensure a seamless and continuous health tracking system, a Web server cloud computing system is implemented into the healthcare service

A. System Architecture

The end-to-end system architecture for this IoT based project involves the hardware, the mobile a application and the cloud. The application has three sub layers named as follows:

Service layer, Platform Application layer and The File Transfer and Writing layer shows how the multiple layers in the system architecture interact with one another. The hardware layer contains the ADC, microcontroller and sensors, which collects the bio signal data and this data is transmitted by the Bluetooth channel on the microcontroller to the Application layer on an IOS device. The Application layer contains three sub layers within the layer itself. The Service Layer is the to op layer in the application layer, which interacts with the hardware layer. The ECG Service is present within the Service layer, which is responsible for retrieval of the bio signal data from the hardware layer and Storing the data in the buffer within ECG Model, which performs the writing of the data.

Relationship Between Cloud Computing and Virtualization

Cloud Computing is a technology, used by several companies who wants to reduce costs, and have access to programs and applications which are not physically installed in their computers or servers. The concept of electricity maybe compared to how this technology works, although the consumer does not know where, and how the power is produced, consumers still have access to power whenever they need just by plugging in an appliance and turning it on. This concept is almost the same as cloud computing, but the main kind of communication used with this technology is the internet. Cloud computing as defined by NIST or National Institute of Standard and Technology is a technology that provides scalable IT capabilities that are offered as services through the internet for multiple users, many users will then share pooled IT resources reducing costs and resulting to greater computing efficiency.

Think of it this way; a company that uses computers will need several systems to provide services, communicate and store information, this also means the more computers you have the more software licenses, servers and storage devices would be needed as your company grows. Behind all these are several people working all day long to make sure that servers, applications and storage devices are working properly and updated. The company will also then need spaces to store these servers and storage devices, and to prevent overheating you will also need cooling appliances which costs money. With cloud computing several of these procurement are taken off. If these company use or migrate to cloud computing they will just need the computers and sometimes a single server to run the business smoothly. All the other computing needs are then outsourced to the clouds, which are servers and storage devices in different locations which can be turned on or off depending on the company’s computing demand. No more expensive software licenses, no more need for several servers and support people to maintain all these. This company will then pay the cloud computing provider as they use the services, it’s like taking a cab and paying through the meter.

Virtualization is a technology which helps companies and individuals to utilize their computers, applications, storage devices and servers more efficiently. This can be defined as running multiple instance of something (Operating System) in something (Computers) when it is only designed to run one instance. There are different types of Virtualisation. Server Virtualisation – Is a type of virtualisation that consolidates multiple physical servers to virtual servers and is then ran on a single physical server. Application Virtualisation – an application is ran on another host where it is installed and is remotely accessed from a different computer. Example of which is desktop virtualization, Presentation Virtualization – runs on a met frame like Citrix, the application is then run in a different host however can also be seen on the clients screen. Network Virtualization – This type of virtualisation uses the network in a carved up way, which can then be run on multiple purposes, through the switch, NIC’s, VLAN’s, storage devices and other devices that can control a network Storage Virtualization – means your storage devices is then consolidated and managed in a virtual storage device, The servers where this is connected to is unaware of the physical location of the virtualized storage device.

Cloud Computing and Virtualization are two different technologies that are most of the time interchanged. These technologies will work without the other. Although, cloud computing is better utilized if desktop Virtualization is done first since most Cloud computing requires multiple virtual servers and storage devices to work or what you may call multitenancy. Virtualization on the other hand, enables a business or an individual to save on their computing needs and resources by making virtualized version of a physical resource in the same resource. For example server A, is only utilized by 30 percent most of the time and server B is utilized only by 50 percent, These two can be combined together by making a virtual server A in server B and therefore not physically using Server A anymore. This means that you save money and resources by eliminating server A from the equation.

Deeper explanation of Server Virtualization

Virtualized servers in a physical server run side by side in the same environment without compatibility issues, because these virtual servers are isolated and are then encapsulated with different layers. From Hardware layer, Virtualization layer and different environments such operating systems and applications. in Hardware layer each virtual server has a dedicated memory, hardrive and processor allocated for it in the physical server. Just like it is an operational Physical server. Most of the time Virtualization converts 20 physical servers to one by turning nineteen of these to physical server into one virtualized server instead.

Cloud computing on the other hand, uses resources that you do not have physical access to, these resources can be servers, applications, operating systems, storage devices and so forth. When you say you compute through a cloud, that means your computing resources are outsourced to vendors while you pay these providers for what you use. Unlike, if you use the conventional computing then you will need all the equipments, people and software for everything to work without problems. Cloud computing means that these resources are then provided to you by a company without you worrying about maintenance, space for your equipments and software licenses because your cloud computing provider will take care of it. All you need to do is log in to your computer, monitor your usage release or employ more servers depending on your computing needs.

What Is Cloud Computing and What Are Public, Private and Hybrid Clouds?

Cloud computing is considered to be the next big computer trend revolutionising the way existing IT infrastructure is run and developed within companies. But what is it? If you type the term into a search engine there will be a whole host of websites that attempt to answer the question but you will often see that many different definitions come back as everyone seems to have a singular take on what cloud computing means to them and their businesses.

Fundamentally, cloud computing is the way that a company will access software, applications, services and data in the future. It is a way that businesses can store and access data through a shared web browser meaning that a company no longer needs physical hardware onsite to store this type of information. The cloud will be provided by a cloud hosting provider meaning a new delivery model for IT services in businesses where the company can gain from economies of scale and virtualised resources. The cloud is an on-demand technology meaning that it can be accessed when required and companies only pay for what is used. It is also a technology that can be accessed from anywhere on a variety of devices including mobile phones; so offering companies greater flexibility and accessibility.

Therefore, put succinctly, cloud computing is the move to make IT management and provision of data, applications and information a service. This service will be run for businesses by their chosen cloud computing provider over the Internet on a consumption-based model.

The security of a company’s data is an important factor in their IT related activities and cloud computing can offer different levels of security to suit business types and needs as data can be held within public clouds, private clouds and hybrid clouds. But what do these terms mean?

Public Clouds

A public cloud as it suggests is information that is held over the Internet for use by the general public in applications such as Gmail and Hotmail. The user of these applications doesn’t know where the data is stored and if the cloud has any downtime it means that the user experiences this downtime as well with no understanding of when applications will be up-and-running again. These types of clouds do not offer any guarantees or service level agreements (SLAs) so are more suited to companies that don’t have business critical applications.

Private Clouds

A private cloud is a cloud service offered to a limited number of people behind a private firewall in a data centre. This type of cloud technology does come with guarantees and SLAs to ensure that data and applications are always available and that there minimal downtime (if any) for a company. This type of cloud is more secure to protect the safety of information.

Hybrid Clouds

A hybrid cloud is an amalgamation of public and private clouds. For example, a business may choose to provide some resources internally (as they have spent money setting-up their existing IT infrastructure) while choosing to outsource some externally.

It can be seen that cloud computing is changing the way that applications and data is both delivered and accessed. When looking for a provider you should look for a company with renowned experience and one that you can fully trust with your businesses software, data and applications.

History Behind Cloud Computing in Healthcare

Cloud computing has come a long way across various phases. Clients can utilize web-based tools or applications through a web browser just as if they were programs installed locally on their own computer. Healthinformatics the wiki of Florida State University says “The term ‘cloud’ was coined as a metaphor for the Internet which originated from cloud figures representing telephone networks, then later followed by depicting Internet infrastructures in computer network maps/diagrams.”

Going back in time, we had the grid and utility computing, the application service provision (ASP), and then Software as a Service (SaaS). However, if you look back, the true concept of delivering computing resources through a global network is really rooted in the 60s. In the year 1969, J.C.R. Licklider through his article Intergalactic computer Network enabled the development of ARPANET (Advanced Research Projects Agency Network). He seemed to project a vision that everyone on the globe be interconnected and access programs and data at any site. Others give credit to computer scientist John McCarthy who proposed the idea of computation being delivered as a public utility.

Since the 60s, cloud computing has evolved over a timeline. Web 2.0 being the most recent evolution. Point to note here is, the Internet only started to offer a significant bandwidth in the nineties. Hence cloud computing for everyone has been something of a recent development. If you have to trace a timeline it looks somewhat like this:

1999 – Salesforce.com (delivering enterprise applications via a simple website)

2002 – Amazon Web Services (providing a suite of cloud-based services including storage, computation and even human intelligence)

2006 – Amazon Elastic Compute cloud EC2 (allowing small companies and individuals to run their own computer applications on a commercial web service)

2007 – Google Docs (Web-based office suite, and data storage service)

There are several other factors that have enabled cloud computing to evolve. These include the virtualization technology, universal high-speed bandwidth, and established standards of universal software interoperability.

Increased storage, flexibility / scalability, and cost reduction are some of the valuable benefits that can be derived, as the prospect that almost anything can be delivered from the cloud, becomes more and more a reality. However security, data privacy, network performance and economics are still concerns that are being addressed through various models of cloud platform delivery such as the Private Cloud, Public Cloud, as well as the Hybrid Cloud solutions.

This brings us to Cloud’s footprints into Healthcare. While, as we have seen above, cloud computing has been around for decades. Hospitals and healthcare systems only recently began to adopt the flexibility, interoperability and affordability of cloud technologies, especially as they implement plans to utilize the federal government’s $20 billion-plus Health Information Technology for Economic and Clinical Health (HITECH) financial incentive programs.

The cloud computing model is very well suited to healthcare applications due to the volume and varied sources of information, that is necessary to be accessed quickly and from any location. After all you have lives at stake. Whether it is for maintaining health records, monitoring of patients, collaboration with peers, prescribing medication, even analysis of data, we will see more and more of healthcare tapping into the cloud. With more attention on the security aspects of Cloud, compliance to Data Privacy standards, advanced interoperability and data sharing, and with a proper DR in place, the cloud can have a real positive impact on Healthcare.

Cloud Computing Advantages to Businesses

From the ‘buzz’ word in the computing world, cloud computing has matured as a full-fledged business strategy that holds many advantages and applications. Even now a lot of enhancements and innovations are going on to make The services faster, better and safer. This article analyses that applications and advantages of cloud computing from a business point-of-view.

In simplest words, cloud computing is the utilization of internet for computing requirements. In an ideal atmosphere businesses only need devices and connectivity to internet. Data, software, applications, storage, networking, security and everything else will be made available to you by your cloud service provider. Currently there is a range of cloud services are available on pay-as-you-go, rental, prepaid and annual fee basis. Some most common cloud applications include Software as a Service or SaaS, Cloud hosting & storage, Security as a Service or SECaaS, Infrastructure as a Service or IaaS, Backup as a Service, Platform as a Service or PaaS, Monitoring as a Service or MaaS and Communication as a Service or CaaS.

Advantages of Cloud Computing to Businesses

The first and foremost important advantage is the cost. Usually with clouds there are no initial investment requirements for infrastructure. Additionally there are no maintenance costs, cost of infrastructure or software upgrade, license fees or in-house IT teams. Usually there is a variety of service packages available to suit every business needs.

The second advantage is the availability of unlimited services. The services may be priced per head or on a flat rate. Most cloud service providers offer the unlimited option on number of users, storage capacity, backup size, user access and almost everything possible. Generally there are no additional costs; even if there is any it still can be very low.

Cloud computing offers easy and universal access of data, applications and procedures. Generally, all cloud services are available any time anywhere there is internet. Moreover, users and businesses not need to bother about the settings and customizations. You can access your data and applications from any computer or device in they way you configured.

Cloud computing offer automated and no-cost updates. The cloud server providers are very keen to offer you top quality services and also automatic updates is one of the basic features that is enclosed on the agreement.

Disadvantages of Cloud Computing to Businesses

Cloud computing with its current setup not suits all kinds of businesses. These services favor large and mid size businesses and businesses who rely highly upon information technology. These services also need stable and reliable internet connectivity; the lack of which can jeopardize the whole idea of cloud services. The data and applications are always hosted on external third-party networks and computers; and data transfers over internet are always prone to attacks.

Cloud Computing and Its Impact on Your Business

The term ‘Cloud Computing’ is one of the most echoed buzzwords in the recent times’ technological expansion. Deliberately or accidentally, you come across cloud storage and cloud computing in everyday life, provided that you are active in the online e-commerce domain.

To be more specific, a majority of people make use of various online video calling facilities like Skype or might regularly access emails for business transactions and also for personal use through Gmail or Yahoo! Here, you access the data or the resources which are lying on a cloud storage environment.

What is cloud computing?

In simple terms, Cloud computing implies delivering hosted services like computing resources or data storage capacity across the Internet. The end-user just needs to have a computer and a high-speed internet access to connect to the cloud where services and resources are shared.

Cloud computing, which has paved the way for a paradigm shift to be introduced in to the IT field, is now being largely used in many fields like web-based software services, on-demand gaming, platform as a service etc. The cloud computing environment is very flexible as the applications or services are platform independent and also the storage location will also be in the cloud, eliminating the need to assign specific hardware to a task.

These services are delivered mainly in three forms like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). In IaaS, the end, the users pay for resources like servers and other infrastructure for a period of time. In PaaS, the platform or system software is accessed from the cloud while in SaaS, the application software and databases are provided by the cloud service provider.

How a cloud helps in your online business?

Developments in the domain of cloud computing and also the interest in this service is on the path of rapid growth as it is used by small and big enterprises on a large scale. Contrary to traditional web hosting services, cloud service is sold on demand and can be treated like it is subscription-based. This is very useful for SMEs (Small Medium Enterprises) who cannot afford to purchase large amount of storage space and hardware resources.

The cloud provider provides the services and resources as per the users demand. It is also very easy and fast to use, as SaaS in cloud computing eliminates the need of installing software in your hardware. You can save a lot of money as cloud provides scalability, enabling you to scale up or down, the use of resources or data from cloud, as per your needs. It also requires less staff as the maintenance tasks, hardware and software are quite minimal.

Thus these services look promising from all perspective, whether for a large enterprise or a small online business.
