Because…
- Run multiple operation systems on one server
- You can have multiple flavors of OS on one server. For example, you can run Linux OS, 1 Windows server 2008 R2 OS and mackintosh on the same server
- Optimize the use of physical hardware
- Allocate hardware resources to different applications based on the utilization. For example, if you have 20GB of RAM(physical) on your host, you may assign variable RAM virtual machines i.e. 8GB to R & D Server VM and 12GB RAM to Production Server VM
- High availability and business continuity gives you the ability to have 99.999% up time
- You can migrating virtual machine(s) from one physical server to another physical server without any downtime.
- It will reduce the operational IT cost and power consumption. For example, instead of buying and running six physical servers, you may be using only two physical servers.
