With flexible network architecture, Cloud Foundation on VxRail systems can support multi-site use cases. Deployment in these cases is not automated. By leveraging additional guidance contained in the VMware Validated Designs, customers can deploy Cloud Foundation environments in dual region and multiple availability zones topologies to support variety of multi-site, disaster recovery and stretched cluster use cases.
VVD supports a multi-region architecture. The term region describes a large geographical separation between data centers. The reference architecture supports network latency between regions up to 150ms. The term availability zones is used for local separation.
The main use cases for regions within the VVD reference architecture are:
VVD includes steps on how to design and implement a dual-region SDDC that supports multiple availability zones (vSAN stretched cluster). Availability zones enhance resiliency of the SDDC and improve SLAs by:
