Message store high availability considerations

High availability refers to the capability of failing over messaging engines between servers. Both file stores and data stores can be deployed to be used in a highly available environment.

Figure 1. Failover of a messaging engine between servers.Two servers, server 1 and server 2, have access to a message store that is either a file store accessed through a network file system or a data store that is accessed through a remote database server. A messaging engine running on one of the servers can be failed over to the other server, and will retain access to the message store.
