What Is Integration Agent?
Integration Agent is a light-weight installation of Integration Server that provides a subset of the functionality available in Integration Server. A light-weight Integration Agent may be a better fit for a solution or environment than the complete Integration Server. Some of the these use cases are:
*A hybrid integration scenario involving webMethods Integration Cloud and partners using Integration Agent.
*Integration Agent installed at a point-of-sale terminal where there are constraints on disk-space and RAM.
