Avaya Aura® Device Services does not support multiple Avaya Aura® Device Services clusters. Instead, you can deploy a geographically distributed cluster, where resources are deployed in multiple data centers to reduce delays. For this purpose, Avaya Aura® Device Services and other components, such as Session Manager, are deployed in each data center. In a geographically distributed system, you must also use a Global Server Load Balancer (GSLB) with location-aware DNS and local or regional load balancers. GSLB provides different routes and addresses based on the location of the client. Load balancer balances traffic between two or more Avaya Aura® Device Services nodes, which may be located in the same data center or in different data centers.

In the following example, there are two data centers with three Avaya Aura® Device Services and three Session Manager servers in each data center. The cluster uses a GSLB to resolve requests to a specific regional load balancer, which then routes these requests only to the Avaya Aura® Device Services nodes within that region.
