Auto Scaling:SetInstancesProtection

Last Updated:Jun 06, 2024

Puts Elastic Compute Service (ECS) instances into the Protected state. When ECS instances are put into the Protected state, they become immune to manual deletion attempts by using the Auto Scaling console or API operations. This operation serves as a robust safeguard, efficiently preventing any inadvertent instance release that could lead to irreversible consequences.

Operation description

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

  • ECS instances will persist in the Protected state, unless you deliberately remove them from this state.
  • Even in scenarios where automatic scale-in actions are initiated due to fluctuations in the number of ECS instances or the execution of event-triggered tasks, Auto Scaling does not remove ECS instances that are in the Protected state from their respective scaling groups. Only after being manually removed from their respective scaling groups can ECS instances that are in the Protected state be released. For more information, see Remove an ECS instance.
  • ECS instances in the Protected state maintain their existing health status even when they undergo stopping or restarting processes.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
