Virtualization for Fast-Growing IT Requirements

The actual need for virtualization basically requires the prior understanding of three things: Why Virtualize? What is Virtualization? And When to Virtualize?

The virtualization technology evolution dates back to the times of main frame computers, where the operators had to utilise huge power resource to run processes. Operating Virtualization addressed this issue by allowing the hardware resource to run multiple operation system images using a single software tool, thus managing the power utilisation in running processes.

Server virtualization is the key aspect of virtualization technology, where the main server is virtualised to create a guest system that exactly works as a main system. A software layer called hypervisor makes this happen by emulating underlying hardware. Here the guest operating system uses the software emulation of the underlying hardware, i.e., virtualized hardware and not the true hardware.

The performance of the virtual system is not exactly the same as that of the true system. Even then the virtualization holds significance as the most applications and guest systems may not demand for full utilization of the underlying hardware.

Thus, the dependence on hardware is alleviated, allowing greater flexibility and isolation of the processes from the main system, whenever needed. Here is where the companies working on multiple applications on multiple platforms can have an advantage of minimization of extra resource utilization.

Virtualization, which was initially confined to server systems, has evolved over the years to suit for networks, desktops, data and applications, among others.

Wings of Virtualization:

Virtualization has spread its wings across six key areas of significance in the IT industry:

Network Virtualization: This reduced the complexity across networks by grouping the available resources in a network, connecting them with independent channels formed as a result of the splitting of available bandwidths. These channels can be linked to devices later, depending on the requirement.
Storage Virtualization: Here, various storage devices are grouped into a single large virtualized storage unit, which is controlled from a central console.
Server Virtualization: This involves the masking of servers so as to limit the server users from accessing server’s complex information, such as physical address, among others, while also ensuring the resource sharing. The software that is used to virtualize the underlying hardware is ‘hypervisor’
Data Virtualization: Here the broader data access is provided to meet the business requirements, while abstracting the very important basic information like storage location, performance, and format.
Desktop Virtualization: Here the main intention is to share the workstation. Instead of server, the workstation load is shared via virtualization, in the name of remote desktop access. As the workstation works in data centre server environment, security and portability are also ensured.
Application Virtualization: Here the application is abstracted from the operating system, and encapsulated. The encapsulated form of the application is used across platforms without having need fo depend on the operating system every time during implementation.

Is Data Recovery Important?

Ask the big IT giants a common question – “In this world of free-flowing data and information, what is THE most singular and important thing that matters the most?” and they will give you a faint smile and tell you that the answer lies in the question itself. If you were not able to guess, it’s DATA. Every bit of it you send over the Net matters equally and secured over their servers for “future reference”.

So imagine the power of data. If data of totally unknown people is so imperative for them, what value can you put on your own data? Priceless probably right! Depending on how sensitive the content of your data is of course.

Reasons for data loss

There are n number of reasons that can lead to your data on the verge of being lost forever because let’s face it all of it is mechanical and electronic. They also have a life, limited durability and are of course susceptible to wear and tear. The most common reasons for data loss are crashing of your hard disk, error in the partitioning, hacking etc. Other reasons include theft of your device, a malware attack, a corrupted OS etc. all of which exposes your data to vulnerability. Data which could be an important presentation for a multi-million dollar deal or years of your memories captured and stored as photographs or anything.

What is data recovery?

As the name suggests naïvely, it is the procedure of attempting to recover all or some of the data present on the hard disk. It may not look or sound like much, but it is a really volatile process. One small mistake and poof! Your data is gone forever.

As soon as you realize you have a failed hard drive, rush it as soon as you can to an expert. Because as days pass, the more complicated, difficult and risky it becomes to attempt a data recovery. This attempt at recovering data recovery is done through various sophisticated methods depending on the situation and the cause of the failed hardware. All these methods ultimately have one and one goal only – to recover all your existing files such as documents, spreadsheets, photos, codes or whatever as well as their backups if you had created any.

What not to do?

Probably the first and the only rule. Don’t try and act smart and start messing around with things that you have no idea about. Instead of solving your problem you will only increase it tenfold.

Second of all, while taking your hard drive for recovery, do not go to an un-trusted place. Either go to the service center or a proper shop which guarantee the safety of ALL your data and who can be trusted when it would come to confidentiality. Basically, a professional workspace because they will actually tell the truth to your face, whether the data is recoverable or not. If yes, how much can be recovered depending on the damage.

What to do

The first course of action is to calm yourself down and ask yourself whether going for a data recovery is actually needed or not. Maybe it is possible you may have kept a backup of it online or someplace else. If that is not the situation, again introspect whether a recovery is of utmost need or not. Because however the sophisticated technology may get, there is always that 1% chance of losing all the data instead.

Your data, however trivial it may seem to you is precious in ways you can’t even imagine. Keep it safe more than you keep yourself. Make and keep backups to get you out of a jam in the event you are on the verge of losing it. However, if it’s not your thing or a habit and find yourself in a situation where recovering your hard drive data is of utmost importance, try out data recovery – they are genuinely the Michelangelo of the art of recovering lost data even when all hope is lost.
