Combination Active/Active High Availability + Disaster Recovery Site + Federated Repositories

If you have resiliency, scalability, and distribution needs, you can combine multiple patterns together such as in this combination of disaster recovery (DR), active/active high availability (HA), and federated repository pattern.

In this pattern, a primary site (called "Region A" in this example) has an active/active HA setup that is federated to Region B. Each region also has a passive DR site set up in case the primary site in that region goes down.
