How Multi-site (WAN) Systems Work

The vFabric GemFire multi-site implementation connects disparate distributed systems. 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 distributed system sites. A wide-area network (WAN) is the main use case for the multi-site topology.
