Benefits of Server Virtualization Technology

What is Server Virtualization Technology?
Server virtualization is a practice growing in popularity amongst business for a number of reasons. Put simply server virtualization is the process of partitioning a physical server so that multiple virtual servers are created. Each virtual server operates independently and runs its own OS and applications making it possible to perform an array of functions such as consolidation, isolation and encapsulation with ease.

Benefits of server virtualization technology are explained below:

Downsizing Server Numbers
Through the consolidation of physical servers it is possible to reduce server numbers. The resulting benefits are reduced costs for air conditioning and power as well as the freeing up of floor space. When consolidation is carried out the virtual servers will still have to be managed and as such certain management software tools will be required.

The Reduction of Overall Costs
Server virtualization helps to reduce overall costs through the consolidation process. This is achieved by lower running costs such as air conditioning, hardware, maintenance and power. Virtualization can also help to reduce costs by increasing the efficiency of server resources which in turn can result in smaller management costs, as in most cases the virtual servers can be operated by a single administrator.

Better Availability
Server virtualization allows administrators to carry out live server migration, the process of migrating a virtual server to another physical server whilst remaining operational. This is extremely beneficial for those with websites as it allows technicians to carry out maintenance tasks on physical equipment without negatively affecting the physical servers, meaning website visitors can still visit and purchase even when the servers are undergoing maintenance.

Easier Testing
Testing new operating systems or other experimental activities can be carried out much easier with server virtualization. As before, the easy partitioning of a physical server means that one group of a business can be carrying out tests whilst the others remain fully functional, once again increasing availability and also providing much more efficient research and development. 
 
The points above give an indication of the benefits of server virtualization technology; essentially through consolidation, and partitioning it is possible for businesses to increase efficiency, reduce operating costs and in the long run, improve profitability.
