A cluster is a group of servers that share replicated repository information. A Jaguar cluster's primary purpose is to provide load balancing and high availability. See Chapter 4, "Load Balancing, Failover, and Component Availability" for more information about load balancing and high availability. Synchronization enables you to connect to the primary Jaguar server in a cluster and distribute repository information to "synchronize" one or more of the other server(s) in the cluster. You can also synchronize non-clustered Jaguar servers. Synchronization provides a quick and easy way to distribute package, servlet, and other configuration information between servers.
