There are some well accepted and inherit benefits to using Virtualization. Here are some of them:
- Reduce the number of physical servers
- Reduce the infrastructure needed for your data center (power, cooling, battery backup, network switch ports, KVM ports and space)
- Reduce administrative overhead because servers can be administered from a single console
- Ability to bring up new servers quickly (it could take days or weeks to put in a new physical server but it could take just a few minutes to create a new virtual server from a template)
- Hardware Independence of virtual servers – a virtual server can run on any host server, regardless of the host hardware
- Because of hardware independence, you receive reduce your disaster recovery cost, complexity, and recovery time
- A “greener” datacenter & server environment due to the consolidation
- Overall, lower TCO of servers
