With flexible network architecture, VMware 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 multiple availability zones topologies to support variety of multi-site and stretched cluster use cases.

Availability zones enhance resiliency of the SDDC and improve SLAs by:

• Allowing identification of separate fault domains within the primary region.
• Leveraging the stretch-clustering capabilities of vSAN to distribute workloads across the availability zones.

VMware Cloud Foundation version 4.2 will support NSX-T Federation. NSX-T Federation is the foundational building block used to support a multi-site dual region deployment of Cloud Foundation. This allows two separate VMware Cloud Foundation instances deployed in data centers at two different geographically distanced regional locations to be connected and provide centralized networking management, consistent networking data services, and centralized network security policy configuration along with enforcement and a synchronized operational state. With NSX-T Federation, VMware Cloud Foundation can leverage stretched networks and unified security policies across multi-region VMware Cloud Foundation deployments providing workload mobility and simplified disaster recovery. The deployment and configuration are done manually following the prescriptive guidance outlined in the VMware VVD documentation.
