How to change the billing method for multiple ECS instances - CloudOps Orchestration Service

Background

When usage requirements change, you may need to switch ECS instances between subscription and pay-as-you-go billing. Doing this manually for multiple instances is inefficient and error-prone. You can use CloudOps Orchestration Service to change the billing method of multiple ECS instances at a time. ECS instances support two billing methods: subscription and pay-as-you-go.

Prerequisites

To change from subscription to pay-as-you-go, see Change the billing method of an instance from subscription to pay-as-you-go.
To change from pay-as-you-go to subscription, see Change the billing method of an instance from pay-as-you-go to subscription.

Procedure

In the OOS console, go to the Automated Task > Public Template page.
In the search box, enter Bulk modify instance charge type, click , and then click Create Execution in the search results.
Click Next Step: Parameter Settings.
Set the following parameters:
1. instanceChargeType: The billing method to apply to the instances.
  1. period: (Required when switching from pay-as-you-go to subscription) The subscription duration. If PeriodUnit is set to Week, the valid values are 1 to 4. If PeriodUnit is set to Month, the valid values are 1 to 12, 24, 36, 48, and 60.
  2. periodUnit: (Required when switching from pay-as-you-go to subscription) The time unit for the subscription duration.
2. includeDataDisks: (Required when switching from pay-as-you-go to subscription) Whether to convert all attached pay-as-you-go data disks to subscription.
3. networkChargeType: The billing method to apply to the network.
4. regionId: The region ID.
5. targets: The target instances.
6. rateControl: (Optional) The concurrency rate for task execution.
7. OOSAssumeRole: (Optional) The RAM role that OOS assumes to perform the task.
Click Next Step: OK, and then click Create.
On the Task Execution Management page, find the new execution.
- If the execution status is Running, the billing method change is in progress.
- When the execution status changes to Success, the operation is complete. You can verify the new billing method on the Instances page in the ECS console.
Note
For details, click Details for the execution. You can view execution logs to track progress in real time.
