Subscription indicates that you must make an upfront payment to use dedicated hosts. You can purchase a yearly or monthly subscription based on your needs. This topic provides an overview of subscription dedicated hosts. It describes the status changes of associated resources after a subscription dedicated host expires. The topic also describes the methods to renew a dedicated host, and view the relevant bills, and the limits that apply when you use a dedicated host.

Billing cycle

A billing cycle starts from the time an instance is purchased, and ends at 00:00:00 on the day following the expiration date. The billing cycle is accurate to the second. The billing cycle follows the UTC+8 time zone.

For example, if you purchased a monthly subscription for a dedicated host at 13:23:56 on March 12, 2018, the subscription expired at 00:00:00 on April 13, 2018.

You can create both subscription and pay-as-you-go ECS instances on a subscription dedicated host. ECS instances created on the dedicated host are not charged for vCPUs, memory, and local disks. However, you are charged for additional ECS resources, such as subscription and pay-as-you-go images, disks, public bandwidth, and snapshots, as shown in the following table.
ECS instance billing method ECS instance status Billing of additional ECS resources
Subscription Running Additional ECS resources, such as subscription images, disks, public bandwidth, and snapshots, are billed based on their individual billing methods.
Manually Stopped Additional ECS resources, such as subscription images, disks, public bandwidth, and snapshots, are billed based on their individual billing methods.
Pay-as-you-go Running Additional ECS resources, such as pay-as-you-go images, disks, public bandwidth, and snapshots, are billed based on their individual billing methods.
Manually Stopped
  • If the no fees for stopped instances (VPC-connected) feature is not enabled, additional ECS resources, such as pay-as-you-go images, disks, public bandwidth, and snapshots, are billed based on their individual billing methods.
  • If the no fees for stopped instances (VPC-connected) feature is enabled:
    • All existing images are retained. The billing for the images continues.
    • Disks are retained and still billed.
    • Public bandwidth:
      • If the ECS instance is assigned a public IP address, the IP address is released and you are no longer charged for the public bandwidth.
      • If the ECS instance is associated with an Elastic IP Address (EIP), the EIP address remains unchanged. The billing for EIP address continues.
      Note After an ECS instance is stopped, the private IP address remains unchanged.
    • Snapshots are retained and still billed.

Pricing

For pricing about dedicated hosts, go to the Dedicated Host section on the Pricing tab of the ECS product page.

Renewal methods

After a billing cycle expires, you can renew your subscription to continue using your dedicate hosts. For more information, see Manual renewal of a dedicated host.

You can also enable the auto renewal feature when you purchase a subscription dedicated host. If you enable the auto renewal feature, Alibaba Cloud automatically bills your credit card or PayPal account associated with your Alibaba Cloud account on the expiration date (T). If the payment fails, Alibaba Cloud bills your credit card or PayPal account on the seventh day (T+6) and the fifteenth day (T+14). If all payment attempts fail, your dedicated host is stopped. For more information, see Enable auto-renewal.

Change billing methods

After you purchase a subscription dedicated host, you cannot change the billing method. However, you can switch the billing method of ECS instances on a dedicated host from pay-as-you-go to subscription. For more information, see Switch the billing method from pay-as-you-go to subscription.

Resource status changes of dedicated hosts after expiration

The status of the resources may change on expiration, based on whether auto renewal is enabled or not.
  • The following table shows the changes to the status of resources when the auto renew feature is not enabled.
    Period DDH ECS instances (vCPU and memory) Additional ECS resources, such as images, disks, public bandwidth, and snapshots
    Within 15 days after the expiration date The dedicated host is shut down at any time from 00:00:00 of the expiration date to 00:00:00 of the following day. ECS instances are automatically stopped after subscription dedicated hosts are stopped.
    15 days after the expiration date The dedicated host is released. All ECS instances on the dedicated host are released. The related data is lost and cannot be recovered.
  • The following table describes the resource status changes that occur if you have enabled the auto renewal feature but your payment fails.
    Period DDH ECS instances (vCPU and memory) Additional ECS resources, such as images, disks, public bandwidth, and snapshots
    Within 15 days after the expiration date Working as expected. Working as expected. Working as expected.
    15 days after the expiration date The dedicated host is shut down at any time from 00:00:00 of the fifteenth day to 00:00:00 of the sixteenth day after the subscription expires. ECS instances are automatically stopped after subscription dedicated hosts are stopped.
    After 30 days since the expiration date The dedicated host is released. All ECS instances on the dedicated host are released. The related data is lost and cannot be recovered.
Note Before an ECS instance is automatically released, you can migrate it to another subscription dedicated host to continue using it. Additional ECS resources can be migrated along with the ECS instance. For more information, see Migrate ECS instances between different dedicated hosts.

Overdue payment

  • For information about the resource status changes that occur after a subscription dedicated host expires, see Resource status changes of dedicated hosts after expiration.

    If you want to continue using the dedicated host, you must settle overdue payments and then renew your subscription. For more information, see Manual renewal of a dedicated host.
