Deploy maximum number of virtualized environments on the same host.

Deploy the virtualized environment on the same cluster if the cluster goes beyond the host boundary.

Segment redundant elements on a different cluster, or ensure that the redundant elements are not on the same host.

Plan for rainy day scenarios or conditions. Do not configure resources only for traffic or performance on an average day.

Do not oversubscribe resources. Oversubscribing affects performance.

Monitor the server, host, and virtualized environment performance.
