The Need Of Virtualization

The Need Of Virtualization

Imagine a situation where you don’t need to maintain a plethora of servers in a gargantuan server room. You don’t have to buy lakhs of PC’s for the work force of your organization. No need to buy individual storage space for your apps. All of this is possible and real with a technology named as Virtualization.

With the growing and scaling technology, the complexity to manage IT infrastructure has also increased to a challenging level. This is one of the major factor due to which efficiency is plummeted. To solve this technical bottleneck a technology comes into play, which is ‘Virtualization’.

With virtualization, there is no need of following the old approach of “One app, One Server”
What is virtualization?

Virtualization as the name signifies is creating a virtual version of something besides the actual and real one. Relevant to IT infrastructure, it can be a virtual version of an operating system, network resources, a storage device or server.
Technically, virtualization means to make or develop manifold, logical instances of software or hardware on a unique and individual physical hardware resource. This methodology simulates (hypervisor) the available hardware and gives all the applications running on top of it, the atmosphere (virtual machine) that is unique to all resources. All the details of the virtual, simulated environment are kept separate from the application.
The most simple and subtle example of virtualization are the partitions we create in the hard disk of our PC or laptop. It is not physical but just a logical division of the hard drive to ease out the data management for users.
Initially the technique of virtualization was limited to server but now it has spread to applications, desktops, data and networks.

Types of virtualization

Spreading up into six areas of IT, virtualization is here to stay to ease out IT management.
1. Network virtualization is a process to unite the available resources in a network by dividing the available bandwidth into independent channels.

  1. Storage virtualization is combining physical storage from various network storage devices into a virtual single storage device which is further managed via central console.
    3. To increase resource sharing and utilization Server virtualization is used by masking servers from users.
  2. By abstracting the traditional technical details of data and its management, Data virtualization is done as per the business needs.
  3. In Desktop virtualization a workstation is created which allows the user to access the desktop remotely.
    6. One of the biggest boon of virtualization is Application virtualization which allow a Windows app to run on Linux and vice versa.

Why we need virtualization

Virtualization, a state-of-art technology is a great boon for an IT industry which allows performing more with less. The main as well as usual goal of virtualization is to centralize the major and administrative tasks with parallel improvisation in scalability and work load.

  • Save resources and money

Every industry has profit-making as their major goal. Virtualization gives you the same while cutting down the need to maintain lot of servers, desktop and data storage machines. All the money invested on the maintenance of these multiple resources is directly cut down to the maintenance cost equivalent to 1-2 resources.

  • Simplified management of data centre

Long gone are the days to manage multiple hard drives and data cables. Now with virtualization just manage 2-3 mega resources and manage zillions of data in fast and easy.

  • Increased IT productivity and efficiency

Now with no hassle and wariness of IT management for big firms, all the technical and software advancement can be done with increased efficiency.

  • Easy disaster recovery

If in case there’s an event of system crash then with virtualization it is easy to detect the loophole as the network or data system is simplified now just to 2-3 layers in-spite of web of hard wires and connection.

  • Enhanced Security

Dropping down to less complex system makes a way to enhance the security level which is easy to implement and more favourable.

Virtualization is a big boon to the tech industry to march ahead without any hassle of hardware or software complexity. If you want to succeed in the IT industry you need to adapt to the latest technologies and virtualization cannot be ignored at any phase of your growth to help you grow in the ever-so-competitive IT industry you can join IIHT to hone your skills in every aspect including virtualization.
