What Is Auto Scaling?

What Is Auto Scaling?


Auto Scaling (AS) is a service that automatically adjusts resources based on your service requirements and configured AS policies. You can specify AS configurations and policies based on service requirements. These configurations and policies free you from having to repeatedly adjust resources to keep up with service changes and demand spikes, helping you reduce the resources and manpower required.


AS provides the following functions:

  • Manage the AS group life cycle, including creating, enabling, disabling, modifying, and deleting an AS group.
  • Automatically add instances to or remove them from an AS group based on configured AS policies.
  • Configure the image, specifications, and other configuration information for implementing AS actions based on the AS configurations.
  • Manage the expected number, minimum number, and maximum number of instances in an AS group and maintain the expected number of Elastic Cloud Server (ECS) instances to ensure that services run properly.
  • Perform health checks for ECS instances in an AS group, automatically detect unhealthy instances, and replace them without manual intervention.
  • View monitoring data of AS groups, facilitating resource assessment.
  • Associate with the Elastic Load Balance (ELB) service to automatically bind load balancers to ECS instances in an AS group.
