8.8. 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 Red Hat 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.
