Chapter 27. Set Up Cross-Datacenter Replication
27.1. About Cross-Datacenter Replication
In Red Hat JBoss Data Grid, Cross-Datacenter Replication allows the administrator to create data backups in multiple clusters. These clusters can be at the same physical location or different ones. JBoss Data Grid's Cross-Site Replication implementation is based on JGroups'
RELAY2
protocol.
Cross-Datacenter Replication ensures data redundancy across clusters. Ideally, each of these clusters must be in a different physical location than the others.
