Cloud Computing Patterns, Mechanisms > Basics > Virtualization Technology > Server Consolidation
The coordination function that is provided by the virtualization software allows multiple virtual servers to be simultaneously created in the same virtualization host. Virtualization technology enables different virtual servers to share one physical server. This process is called server consolidation and is commonly used to increase hardware utilization, load balancing, and optimization of available IT resources. The resulting flexibility is such that different virtual servers can run different guest operating systems on the same host.
These features directly support common cloud computing features, such as on-demand usage, resource pooling, elasticity, scalability, and resiliency.
