Auto Scaling：SetInstancesProtection

Usage notes

After ECS instances enter the Protected state, they become subject to the following restrictions:

• After you put an ECS instance into the Protected state, the instance remains in the Protected state until you move the instance out of the Protected state.

• After you put an ECS instance into the Protected state, Auto Scaling does not remove the ECS instance even if a scale-in caused by changes in instance quantity or event-triggered tasks occurs. ECS instances that are in the Protected state can be released only after you manually remove the ECS instances from their respective scaling groups. For more information, see Remove an ECS instance.

• ECS instances in the Protected state maintain their health status even when they undergo stopping or restarting processes.
