A friend recently asked if we were going crazy with defining virtualization within an already virtual world. Many would share his thought. The term ‘virtual’ has taken a nested avatar, one within another. Server virtualization is one such concept. However, if you look closely, you’ll realize that though the web is virtual, the web server is real, absolutely tangible. Yes, logical divisions of this physical server are what server virtualization is all about.
So, what is the big deal in partitioning the server? Imagine a clothes cabinet without racks. Now, the only way you can arrange the cabinet is by stacking clothes, which, of course, is not a good idea. Now, if you build racks in this cabinet, you get smaller cabinets to arrange your clothes in, in a much organized way. Yes, I know you would point out that the divisions here are physical. I agree they are. That’s the difference between organizing a server: you can partition it logically and use each partition as a separate server. These servers are called Virtual Private Servers, and rightly so.
As we mentioned, virtualization of servers makes way for better organization and management. Wondering what else it has to offer? Read on.
- It helps reduce costs as you don’t need to buy additional hardware. Virtualization also helps cut down on maintenance costs that you would incur if you had more physical servers.
- It offers increased security as the virtual servers are independent of one another.
- It helps save space as you don’t need to buy additional physical servers.
- Virtualization assures high availability of your applications as another server can take over when one fails. Thus, it also offers business continuity.
