During the lifetime of a vRealize Automation installation, new use cases arise that require the implementation of new service catalog items and features. Customers might make additions to the virtual machine lifecycle workflow or have a need for new Day-2 operations to be exposed to users for a better user experience. The testing of new extensibility features does not impact the immediate or long-term usability of a production instance of vRealize Automation. Therefore, VMware recommends that a development instance of vRealize Automation be implemented to develop new service catalog content and features.
