This topic describes the pricing of Auto Scaling.

You can activate Auto Scaling for free. However, if Auto Scaling creates Elastic Compute Service (ECS) instances based on scaling configurations or you add existing ECS instances to Auto Scaling, you must pay for these ECS instances. For more information about the pricing of ECS, see Billing overview. The feature of no fees for stopped instances is only available to pay-as-you-go ECS instances whose network type is VPC. For more information, see No fees for stopped VPC instances.
Note Auto Scaling can automatically create only pay-as-you-go and preemptible ECS instances.
