Multi-region datacenters

As your solution expands geographically, and the number of sites grows, it becomes reasonable to define multiple regions. Each region would be comprised of a hub-and-spoke topology as described in one of the previous examples:

• Single datacenter (active-passive gateway)
• Multiple datacenters (primary/secondary gateways)

Branch devices connect to the gateway devices in their region, and gateways are interconnected between regions in a full mesh design.
