What Are AMS Change Types?

Welcome to the AWS Managed Services (AMS) Change Type Reference. Change Types are the method you use when submitting a request for change (RFC) to indicate what change you want and how it should be implemented.

Change types have a four-part classification scheme: category, subcategory, item, and operation, "CSIO" for short. The category and subcategory are higher-level concepts, and the item and operation specify an entity and the operation that is applied to the entity. For example, the change type that creates an EC2 instance has the classification Deployment | Advanced stack components | EC2 stack | Create, and the change type that requests administrative access to that instance has the classification Management | Access | Stack admin access | Grant. For more information about change types and requests for change (RFCs), see Change management in the AMS User Guide.

This document provides a reference for all of the AMS change types. Any request for change (RFC) that you submit to AMS requires that you specify a change type. If none of the existing change types are appropriate for your request, you can use the Management | Other | Other | Create or Management | Other | Other | Update classifications.

To learn more about using change types, see the following topics in the AMS User Guide:

For example walkthroughs of each change type, see the Additional information section for the change type, Change Types by Classification.
