use resource groups to group ECS resources and implement hierarchical management of resources for multiple users or projects - Elastic Compute Service

Group ECS resources by usage, permissions, or region for hierarchical multi-user and multi-project management.

Supported ECS resources

ECS resources that support resource groups include instances, disks, images, elastic network interfaces (ENIs), security groups, snapshots, launch templates, and key pairs.

Usage notes

Note the following items when you use resource groups:

A resource group can contain ECS resources in different regions.

For example, Resource Group A can contain instances from both the China (Beijing) and China (Hangzhou) regions.
Resources in different resource groups under the same account can be associated if they reside in the same region.

For example, an instance in the China (Beijing) region of Resource Group A can be added to a VPC in the China (Beijing) region of Resource Group B.
Resource groups inherit the global permissions of RAM users. If a RAM user has permissions to manage all Alibaba Cloud resources, the RAM user can view all resource groups in the Alibaba Cloud account.
