A cluster is a group of servers that share replicated repository information. An EAServer cluster’s primary purpose is to provide load balancing and high availability. See Chapter 7, “Load Balancing, Failover, and Component Availability” for more information. Synchronization enables you to connect to the primary server in a cluster and distribute repository information to “synchronize” one or more of the other servers in the cluster. You can also synchronize nonclustered servers. Synchronization provides a quick and easy way to distribute package, servlet, and other configuration information between servers.
