Use the multi-site configuration to scale horizontally between disparate, loosely-coupled clusters. A wide-area network (WAN) is the main use case for the multi-site topology.

  • How Multi-site (WAN) Systems Work

    The VMware GemFire multi-site implementation connects disparate clusters. The systems act as one when they are coupled, and they act as independent systems when communication between sites fails. The coupling is tolerant of weak or slow links between cluster sites. A wide-area network (WAN) is the main use case for the multi-site topology.

  • Multi-site (WAN) Topologies

    To configure your multi-site topology, you should understand the recommended topologies and the topologies to avoid.

  • Configuring a Multi-site (WAN) System

    Plan and configure your multi-site topology, and configure the regions that will be shared between systems.

  • Filtering Events for Multi-Site (WAN) Distribution

    You can optionally create gateway sender and/or gateway receiver filters to control which events are queued and distributed to a remote site, or to modify the data stream that is transmitted between GemFire sites.

  • Resolving Conflicting Events

    You can optionally create a GatewayConflictResolver cache plug-in to decide whether a potentially conflicting event that was delivered from another site should be applied to the local cache.
