You create resource mappings between the vRealize Automation catalog resource type and the vRealize Orchestrator inventory type to manage resources provisioned outside of XaaS.

For example, you might want to create an action so that users can take a snapshot of their Amazon machines. For this action to work on an Amazon machine provisioned, the three components involved, XaaS, vRealize Orchestrator, and IaaS, need a common language You create that common language by adding a resource mapping in XaaS that runs a vRealize Orchestrator scripting action or workflow to map the IaaS Cloud Machine resource type to the vRealize Orchestrator AWS:EC2Instance inventory type.

vRealize Automation provides resource mappings, and the underlying vRealize Orchestrator script actions and workflows, for vSphere, vCloud Director, and vCloud Air machines.
