By running multiple operating systems and multiple applications on the same physical server, virtualization lets you reduce costs while increasing the efficiency and utilization of your existing x86 hardware.
- Reduce capital and operating costs. Server consolidation lets you get more out of your existing hardware by running multiple virtual machines (VM) on a single physical server. Fewer servers means lower capital and operating costs. For the most cost savings, make sure you go with a virtualization solution that has the highest VM density per host.
- Deliver high application availability. Integrated availability and fault tolerance protects all your virtualized applications. Should a node or server ever fail, all its VMs are automatically restarted or continued on another machine, with no downtime or data loss.
- Improve business continuity. Virtualization makes it easier to survive unplanned potential IT disasters. You can move VMs from one server to another in a different location.
- Increase IT productivity. Streamlined and automated management tasks mean you’ll spend less time on maintenance and more time on innovation.
- Improve responsiveness. Virtualization lets your business scale rapidly because you can deploy desktops, applications and servers quickly and flexibly.
Virtualization Is Not Cloud Computing
Cloud computing is essentially the delivery of shared computing resources (software and/or data) on demand through the Internet. Cloud computing is one thing you can do with virtualization. Whether or not you are in the cloud or not, you can start by virtualizing your servers and then move to cloud computing for even more agility and increased self-service.
Virtualization Is Not Just about Servers
While most people start with server virtualization, there is much more. As you move toward a Software-Define Data Center, You’ll move past the limits of hardware-centric architecture with:
