What is Server Virtualization Technology?
Server virtualization is a practice growing in popularity among businesses for several reasons. Simply put, server virtualization is the process of partitioning a physical server to create multiple virtual servers. 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.
The benefits of server virtualization technology are explained below:
Downsizing Server Numbers
Consolidating physical servers can reduce server numbers. The resulting benefits are reduced costs for air conditioning and power and freeing up floor space. When consolidation is carried out, 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, migrating a virtual server to another physical server while remaining operational. This is highly 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
Server virtualization makes testing new operating systems or other experimental activities much easier. As before, the easy partitioning of a physical server means that one group of businesses can carry out tests. In contrast, 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, businesses can increase efficiency, reduce operating costs, and, in the long run, improve profitability.
