Load Balancing in Multi-site Installations - Early Access

GemFire Enterprise now allows you to balance the load of gateway communication between multiple VMs. The basic approach is to define multiple gateway hubs and then split outgoing region event messaging between them.

With the new functionality, you can:

■	Specify multiple gateway-hubs in your cache

■	Indicate for each VM whether a hub should start as primary or secondary

■	Point each gateway-enabled region to a specific gateway-hub

Only the primary hub instances send region events to remote sites. By splitting your hub primaries between multiple VMs and splitting your region events between hubs, you can achieve a level of load balancing in your outgoing hub messaging.
