The architecture and infrastructure selected for the management clusters supporting single or multitenant environments are transparent to vCloud consumers.

The definition of the level of service for each offering of the Cloud Service Provider must declare the expected overall availability of the infrastructure to allow the consumer of the vCloud services to correctly plan the positioning of its workloads depending on their criticality and on business needs.

The Cloud Management Platform, its architecture, and its availability are critical for delivering a resilient tenant infrastructure. If a Service Level Agreement is defined between the Cloud Service Provider and the vCloud consumers, the level of availability for the CMP must match or be at least comparable to the highest requirement defined across the SLAs to maintain both the management cluster and the resource groups in the same availability zone.
