Do you have high availability requirements for your Mule application? Mule High Availability provides basic failover capability for Mule. When the primary Mule instance become unavailable (e.g., because of a fatal JVM or hardware failure or it’s taken offline for maintenance), a backup Mule instance immediately becomes the primary node and resumes processing where the failed instance left off. After a system administrator has recovered the failed Mule instance and brought it back online, it automatically becomes the backup node.

Seamless failover is made possible by a distributed memory store that shares all transient state information among clustered Mule instances, such as:

  • SEDA service event queues
  • In-memory message queues

Mule High Availability is currently available for the following transports:

  • HTTP (including CXF Web Services)
  • JMS
  • WebSphere MQ
  • JDBC
  • File
  • FTP
  • Clustered (replaces the local VM transport)
