AS offers the following advantages to your application system:

  • Enhanced cost management

    AS adds resources to your application system when the access volume increases and reduces extra resources from the system when the access volume drops, reducing your cost.

  • Improved availability

    AS ensures that the application system consistently has a proper resource capacity to comply with access volume requirements. When AS works with a load balancer, the AS group automatically adds available instances to the load balancer listener, through which incoming traffic is evenly distributed across the instances.

  • High error tolerance

    AS monitors the instance status in the application system. After detecting an unhealthy instance, AS replaces it with a new one. In addition, AS evenly distributes instances to AZs.

  • Appropriate number of ECSs

    AS ensures that an appropriate number of ECSs handle application loads. During the creation of an AS group, you can specify the minimum and maximum numbers of instances in each AS group. After AS policies are configured, AS increases or reduces the number of ECSs. The number will never be lower than the minimum value or greater than the maximum value when application requirements increase or decrease. In addition, you can set the expected values in the AS group when or after creating the AS group, and AS ensures that the number of ECSs in the AS group is always the expected value.
