This is another recommended scenario where the devices have been distributed across geographical locations in two data centers and each data center maintains HA for the Tellaro nodes. The devices in this scenario are behind a load balancer; the transactions can go to either device in the primary data center cluster. As before, the data are replicated asynchronously over ports 7001, 7002, and 7003.

In this configuration, the applications are shielded from having to communicate with the Tellaro nodes directly, and assume that if the entire data center (where Tellaro 01 and Tellaro 02 are placed) fails, the load balancer can be routed—manually or automatically—to point to the data center where Tellaro 03 and Tellaro 04 are located.
