  description: 'The AWS Application Auto Scaling API lets you register and manage scalable

    targets (DynamoDB, ECS, Aurora, ElastiCache, Lambda provisioned concurrency,

    SageMaker endpoints, AppStream fleets, EMR, Keyspaces, Neptune, MSK, Spot

    Fleet, WorkSpaces, and custom resources), configure scaling policies and

    scheduled actions, and inspect scaling activity. It is an AWS query API

    transported over HTTPS POST to a regional endpoint, with requests signed

    using AWS Signature v4. This file is an API Evangelist research artifact

    for the scalable-systems topic.
