Deletes a scaling group.

Description

Before you call the DeleteScalingGroup operation to delete a scaling group, take note of the following items:

  • If you delete a scaling group, the scaling configuration, scaling rules, scaling activities, and scaling requests related to the scaling group are also deleted.
  • If you delete a scaling group, the scheduled tasks and event-triggered tasks of the scaling group are not deleted. The Server Load Balancer (SLB) instances and ApsaraDB RDS instances with which the scaling group is associated are also not deleted.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.
