Enterprise Integration Patterns Using Mule

Standard Support for Mule 4.1 ended on November 2, 2020, and this version of Mule reached its End of Life on November 2, 2022, when Extended Support ended.

Deployments of new applications to CloudHub that use this version of Mule are no longer allowed. Only in-place updates to applications are permitted.

MuleSoft recommends that you upgrade to the latest version of Mule 4 that is in Standard Support so that your applications run with the latest fixes and security enhancements.

Enterprise Integration Patterns are accepted solutions to recurring problems within a given context. The patterns provide you with a framework for designing and building messaging and integration systems, as well as a common language for teams to use when architecting solutions.

Mule runtime engine supports most of the patterns shown in the Enterprise Integration Patterns book written by Gregor Hohpe and Bobby Woolf.

Mule reduces the effort required when building integrations by implementing the patterns that you use to design solutions. You can then simply configure and use these same patterns in Mule.

Mapping Enterprise Integration Patterns into Mule Objects

Review the following list of Enterprise Integration Patterns that can be mapped directly to Mule objects:

Integration Styles

Pattern	Mapping to a Mule Object
File Transfer	File Connector
Shared Database	DataBase Connector
Remote Procedure Invocation	Mule APIs are meant to work like this (or even doing requests to external APIs).
Messaging	Mule is all about Messaging.
