Removing an ECS from an ECS Group

Function

This API is used to remove an ECS from an ECS group. After being removed, the anti-affinity policy will not take effect on this ECS and other ECSs in the same ECS group.

Constraints

Only the anti-affinity policy is supported. ECSs in the same ECS group are deployed on different hosts, improving service reliability.

This API supports checking fine-grained permissions for enterprise projects. For details, see ecs:cloudServers:deleteServerGroupMember.
