What is Server Virtualization?
Computer machines that host files and applications have to be powerful. Some have central processing units (CPUs) with multiple processors that give these servers the ability to run complex tasks with ease.
System administrators usually dedicate each server to a specific application or task. Many of these tasks don’t play well with others, each needs its own dedicated machine.
One application per server also makes it easier to track down problems as they arise. It’s a simple way to streamline a computer network from a technical standpoint.
Server Virtualization Technology
There are a couple of problems with this approach, though. One is that it doesn’t take advantage of modern server computers’ processing power. Most servers use only a small fraction of their overall processing capabilities. Another problem is that as a computer network gets larger and more complex, the servers begin to take up a lot of physical space. A data center might become overcrowded with racks of servers consuming a lot of power and generating heat.
Server virtualization is the masking of a single computer server machine into multiple virtual servers environments to support several applications for better optimization of resources and reduce power consumption.
A software application is used to divide one physical server into multiple isolated virtual environments.
Advantages of adopting Server Virtualization
- Reduce number of servers
- Reduce TCO
- Improve availability and business continuity
- Increase efficiency for development and test environments
- Improve availability of your virtual environment
- Assume a mixed virtual environment
