For most of the people server virtualization sounds something complex, but if you will go through it you will find it much more easier. Virtualization is considered as one of the mainstream technology and it is the popular solution for data center management for every type of company. Understanding the basics server virtualization allows you to run multiple guest operating systems which can be either same or different on a host operating system on a physical server. Operating systems are divided in order to reside each application on its own virtual machines or virtual server on the hardware platform. Benefits associated with virtualization are endless and it is specially very much good for small business. Most important benefit is lowering the cost for the owner and it also includes many smaller benefits like:
- Improve physical space in Data center and also reduce server sprawl.
- Hardware maintenance cost is reduced since number of physical servers are also reduced.
- Speed up the network thus making provision for new services.
- Performance and resource utilization is improved.
- Applications are quickly developed and organized and downtime is avoided due to maintenance windows.
- Flawlessly mange and scale the infrastructure based on various industrial demands.
There are many software which helps in organizing server virtualization. Some of the most famous and most conveniently applied virtualization servers are:
