Reserved instances allow you to view the purchased pay-as-you-go instances that the reserved instances match. If pay-as-you-go instances are displayed in the matched instance list of a reserved instance, these pay-as-you-go instances match the reserved instance. However, the reserved instance is not necessarily applied to all these pay-as-you-go instances. You can check your bills for usage details of the reserved instance.


  1. Log on to the ECS console.
  2. In the left-side navigation pane, choose Instances & Images > Reserved Instances.

    Note The pay-as-you-go instances created by E-MapReduce (EMR) or Alibaba Cloud Container Service for Kubernetes (ACK) are not displayed in the matching list of reserved instances. However, these pay-as-you-go instances can also benefit from billing discounts of reserved instances.
