Today, AWS Managed Services (AMS) released a feature set of usability improvements for the AMS Console. AMS allows you to choose from a catalog of over 30 AWS services, and over a hundred different Change Types (CTs), to deploy or update resources into your AMS environment. This release allows you to use a keyword search to find CTs, and an option to filter your results by most recently or frequently used. This simplifies your ability to find what you need based on your usage.
