The Instance page of the Elastic Compute Service (ECS) console provides a feature for performing batch operations on multiple instances in a region. This allows you to maintain and manage the instances at once, such as configuring instance attributes, upgrading or downgrading configurations, and sending commands.
Procedure
Go to the ECS console-Instance page.
Select the instances that you want to manage in the current region.
Click More in the lower-left corner of the Instance page, as shown in the figure. In the pane that appears, select an action. Then, provide the required information as prompted to complete the batch operation.
Use CloudOps Orchestration Service (OOS) to perform batch operations in the following scenarios:
Perform batch operations on ECS instances across Alibaba Cloud accounts or regions.
Perform batch operations on multiple types of cloud resources.
Integrate the batch operation feature into your business systems or perform scheduled or event-triggered batch operations.
