Description

With Application Auto Scaling, you can configure automatic scaling for the following resources:

  • Amazon ECS services
  • Amazon EC2 Spot Fleet requests
  • Amazon EMR clusters
  • Amazon AppStream 2.0 fleets
  • Amazon DynamoDB tables and global secondary indexes throughput capacity
  • Amazon Aurora Replicas

  • AWS Lambda function provisioned concurrency
  • Amazon Keyspaces (for Apache Cassandra) tables
API Summary

The Application Auto Scaling service API includes three key sets of actions:

  • Register and manage scalable targets - Register AWS or custom resources as scalable targets (a resource that Application Auto Scaling can scale), set minimum and maximum capacity limits, and retrieve information on existing scalable targets.
  • Configure and manage automatic scaling - Define scaling policies to dynamically scale your resources in response to CloudWatch alarms, schedule one-time or recurring scaling actions, and retrieve your recent scaling activity history.
  • Suspend and resume scaling - Temporarily suspend and later resume automatic scaling by calling the RegisterScalableTarget API action for any Application Auto Scaling scalable target. You can suspend and resume (individually or in combination) scale-out activities that are triggered by a scaling policy, scale-in activities that are triggered by a scaling policy, and scheduled scaling.
