Resource sizing for a vCloud depends on the corresponding service definition. A private vCloud service definition might not explicitly call out a required number of workloads to support. In this case, use the initial sizing for a public vCloud as guidance.

For a public vCloud, initial sizing for the vCloud consumer resources can be difficult to predict due to lack of data points on expected consumer uptake. The provider is also not aware of existing usage statistics for vCloud workloads.

The sizing examples in the next sections come from Service Definitions and can assist with initial sizing of the vCloud environment.
