When you deploy a geographically distributed system, consider the following:
Users in a specific region resolve the Avaya Aura® Device Services cluster FQDN to a load balancer that is deployed in that region. The region-specific load balancer must be configured to route requests to the Avaya Aura® Device Services cluster FQDN to the Avaya Aura® Device Services nodes within that region only.
GSLB must route requests to the Avaya Aura® Device Services service port which is by default 443.
If you use the Utility Server on Avaya Aura® Device Services, you must use an additional external load balancer for the Utility Server virtual IP address.
On the Avaya Aura® Device Services administration portal, you must enable the use of an external load balancer. For details, see Administering Avaya Aura® Device Services.
