Benefits of Virtualized IT Infrastructure

Server Virtualization 4

Consolidation of servers

One of the main advantages of virtualization is consolidation of servers, ie, less servers as physical machines are  able to do the same thing. This means direct cost savings in IT sector as the initial costs and maintenance costs. If you perform the virtualization server existing potential, it means you have one or more servers for redundancy the same number of applications. Redundancy of servers can be used to increase the number of applications. It should be noted that for each installation of an application, whether installed in a virtual or non-virtual environment, you will need to obtain a license, because virtualized application must have its own license.

Improving maintenance

The management of virtual machines is much easier than managing conventional computers. The hardware upgrade can be done just by clicking a few buttons, instead of extinguishing the server, install the hardware, confirmation of changes and re-boot the system. Also, the management of virtual machines can be performed through the console, thus reducing the time it takes to access the physical server. Also, it is easier to perform maintenance on a smaller number of servers.

Saving electricity

As a rising cost of electricity, the cost of electricity for a server is no longer negligible. For instance, in some EU countries in the last 5 years the price rose by 35%. According to some estimates, between 4% -7% of the IT budget is spent on electricity bills. Servers are becoming smaller, are more powerful, but because becoming “more hungry” for electricity. It carries power and heat production which has led to the first server, then the server room. If we assume that the average lifetime of a server is about 3 years, it is estimated that in the three years that server will spend the amount of electricity for their own work and for cooling as has been the cost when it was purchased. This means that each server purchased, after a period of 3 years, spent another means of such a server. Virtualization reduces the number of servers required for a particular job. It directly means that virtualization saves money.

Reducing the time required for Backup and Recovery

Any big company that understands the importance of IT infrastructure has developed a plan for Backup and Recovery procedure. In this regard, during the Recovery procedure approved x hours. That means that a company is resigned to the fact that sometimes you have to x hours to pause in their work, until Recovery procedure is not completely finished.

Backup procedure for virtual machine simplest means copying a file. It is true that the file can be quite large (several GB), but only one. Recovery procedure is fairly simple as the virtualization platform knows how to recognize when a server is not in use and automatically redirect part of its work to other servers. This will burden the remaining servers until some time in the system does not introduce new physical server, but the work will not stop. It is true that some data will be lost, especially those who were in the physical memory of the broken server, but after restarting the process or that application, the company can continue its work. This whole procedure of transferring applications are performed automatically, which means that downtime is measured in minutes, not hours.

Software Testing

In the process of developing new software, in certain stages it takes its testing. If done right software for a particular purpose and for certain customer, it is understood that software should be tested in one hardware environment in which you will need to run the client. But why buy hardware that is identical to the hardware when the client can process this virtualization hardware to simulate. This gets the identical hardware platform as the client, without the need to spend money to purchase hardware. You can place the client still has some outdated hardware that we can no longer be purchased.

There is a situation in which you have to test the software to communicate with specific applications that already exist in the client. Of course the client will not allow his real network to test untested software, which could be threatened his daily work. The whole configuration of hardware and software can simulate the techniques of virtualization and tested without any consequences.

Keeping compatibility

Sometimes (more often than I like to admit) are going to use a software that we carry out work for years without the need to change. It is usually a software for specific purpose such as accounting, finance or simplest software running on a smaller accounting firm. With the advancement of computer technology, hardware changes every few years, and with it comes a new software, a new operating system and so on. After a while you will come when our program can not work with the new operating system and have or obtain a new version of the program (usually impossible) or buy straight but obsolete hardware to be able to keep the old operating system (even impossible). The solution is very simple, the new hardware with virtualization techniques to install the old operating system and software that we used and it will work as long as you work. This “technique” used by today’s users of Windows XP or Windows Vista, who favorites some older DOS games, so today’s play.

Saving space

Conserving space that is obtained by consolidating servers can be significant. Estimates of Microsoft, the techniques of virtualization can reduce the number of servers at a ratio of 5:1 to 8:1 in some cases. This means that a virtualized server is able to perform the work of 5-8 nonvirtualized servers. Conserving space is particularly important in those situations where the server room can be allocated a separate room, so the server must be standing in office space. In that case it does not matter whether you need to make room for one or 5-8 servers.
