6.8.2. Replication Traffic on Internal Networks

Some cloud providers charge less for traffic over internal IP addresses than for traffic over public IP addresses, or do not charge at all for internal network traffic (for example, GoGrid). To take advantage of lower rates, you can configure JBoss Data Grid to transfer replication traffic using the internal network. With such a configuration, it is difficult to know the internal IP address you are assigned. JBoss Data Grid uses JGroups interfaces to solve this problem.
