This topic describes how to move an ECS instance out of the Standby state. You can move an instance out of the Standby state to reuse it.

Background information

After an ECS instance in a scaling group is moved out of the Standby state:
  • The ECS instance enters the In Service state.
  • If a Server Load Balancer (SLB) instance is associated with the scaling group to which the ECS instance belongs, the ECS instance is added to the backend server group of the associated SLB instance again. By default, the SLB weight value of the instance is 50.
  • When the ECS instance is stopped or restarted, its health status is updated.
  • When a scale-in event is triggered in the scaling group, the ECS instance can be removed from the scaling group.
    Note If the lifecycle of the ECS instance is managed by the scaling group, the ECS instance is released. Otherwise, the ECS instance can still run normally. For more information about the lifecycle management of ECS instances, see ECS instance lifecycle.
