Topologies and Communication explains how to plan and configure VMware GemFire member discovery, peer-to-peer and client/server communication topologies.
Topology and Communication General Concepts
Before you configure your VMware GemFire members, make sure you understand the options for topology and communication.
Use peer-to-peer configuration to set member discovery and communication within a single cluster.
In the client/server architecture, a relatively small server farm manages the cached data of and access to the same data for many client applications. Clients can update and access data efficiently, leaving the servers to manage data distribution to other clients and any synchronization with outside data stores.
Multi-site (WAN) Configuration
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.
