If you resize down, the Instance Group Manager service deletes instances fromthe group until the group reaches the desired size. Instances are deleted inarbitrary order but the Instance Group Manager takes into account someconsiderations before it chooses which instance to delete. For more information,seehttps://cloud.google.com/compute/docs/reference/rest/v1/instanceGroupManagers/resize.

If you resize up, the service adds instances to the group using the currentinstance template until the group reaches the desired size.
