In an SDDC, availability zones are collections of infrastructure components. Availability zones are isolated from each other to prevent the propagation of failure or outage across the data center. Use regions to place workloads closer to your customers, comply with data privacy laws and restrictions, and support disaster recovery solutions for the entire SDDC.
This hybrid cloud design uses an on-premises protected region (Region A) for SDDC management components with one or two availability zones, an on-premises recovery region (Region B) with a single availability zone, and a region on VMware Cloud on AWS (Region C) with a single availability zone. You can place workloads in each availability zone and region. You can expand the design to include multiple availability zones.
