What is server virtualization anyway? It simply refers to the logical partitioning of servers into several sub-servers. Each of these sub-servers is referred to as a virtual server. You may wonder if virtualization makes any difference given the physical server remains the same. When you cannot afford to own a complete server, you have to make-do with a shared server. However, sharing leads to battling for resources with others sharing the server with you. Now, imagine a chunk of this server given to you that you don’t have to share with others. That’s how a virtual server helps you.
Even if you own entire servers, you can get more benefits off them by partitioning them into logical servers. You continue to own the same number of servers but you get to do more. You can install a different operating system on each virtual server. Since you don’t need to buy additional hardware for this, you save money. In fact, you also save space in your data center.
Server virtualization provides for better utilization of available resources. It also offers increased security. If one virtual server faces a problem, other virtual servers don’t crash. In fact, a virtual server can be use as a honeypot to trap viruses and other malicious programs. It is also used as a sandbox to test various applications.
Your network applications remain available even if a server fails. Server virtualization, thus, ensures high availability and offers business continuity. Its features indicate that virtualization is good for businesses.
