Use peer-to-peer configuration to set member discovery and communication within a single cluster.
Peer members discover each other using one or more locators.
By default VMware Tanzu GemFire uses TCP for communication between members of a single cluster. You can modify this at the member and region levels.
In a peer-to-peer configuration, you can organize members into logical member groups and use those groups to associate specific data or assign tasks to a pre-defined set of members.
