This topic introduces the billing information of Auto Scaling.
Auto Scaling is a free service, however, all ECS instances that Auto Scaling automatically creates, or manually adds, to a scaling group will be charged according to their instance types. For pricing information of ECS instances, see pricing overview. The No fees for stopped instances feature only applies to VPC-connected Pay-As-You-Go instances. For more information, see No fees for stopped VPC instances.
Note You can only select Pay-As-You-Go or Preemptible Instance when creating a scaling configuration.。
