By using multiple regions, you can place workloads closer to your customers. For example, you can operate one region on the US East Coast and one region on the US West Coast, or operate a region in Europe and another region in the US.
The Consolidated SDDC supports a single region only. See VMware Validated Design for Software-Defined Data Center if your environment must consist of multiple regions.
Using regions has the following advantages:
Support disaster recovery solutions. One region can be the primary site and another region can be the recovery site.
Address data privacy laws and restrictions in certain countries by storing tenant data in a region in the same country.
The distance between regions can be large. The latency between regions must be less than 150 ms.
This validated design uses one example region, San Francisco (SFO) .
