Use ModifyInstanceChargeType to change the billing method of ECS instances - Elastic Compute Service - Alibaba Cloud - Elastic Compute Service

Modifies the billing method of ECS instances. Batch modification is supported.

Operation description

Before you begin

Make sure that you fully understand the subscription, pay-as-you-go, and other billing methods and pricing of Elastic Compute Service (ECS).
Make sure that the target instances are in the Running (Running) or Stopped (Stopped) state and that your account has no overdue payments.
After the billing method is changed, automatic payment is enabled by default. Make sure that your account balance is sufficient. Otherwise, abnormal orders are generated, and you can only cancel the orders. If your account balance is insufficient, you can set the AutoPay parameter to false. In this case, unpaid orders are generated, and you can log on to the ECS console to complete the payment.

Precautions

Subscription to pay-as-you-go:
When you convert a subscription instance to a pay-as-you-go instance, the new billing method covers the entire lifecycle of the instance. You receive a refund for the price difference, which is returned to your original payment method. Vouchers that have been redeemed are not refundable.
- Refund rules: The refund amount that you can freely use within a month is limited and does not carry over. After the refund quota is exhausted, you can only switch between billing methods in the next month. The refund quota consumed by a single billing method switch is calculated by using the following formula: vCPUs × (refund days × 24 ± floating hours). For more information, see Change the billing method from subscription to pay-as-you-go.
Pay-as-you-go to subscription:
- All pay-as-you-go data disks attached to the instance can be converted to subscription data disks at the same time.
- If a release time has been set for the pay-as-you-go instance, you cannot call this operation. For more information, see Change the billing method from subscription to pay-as-you-go.
- If the instance is in economical mode, start the instance first.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
