Tags are used to identify cloud resources. You can use tags to classify resources that have the same characteristics in multiple dimensions. This facilitates resource management.
- Query cloud resources by tag
You can add tags to applications and clusters, and then query these resources by tag in the console. For more information, see Filter resources by tag.
- Use tags to enforce access control on resources
You can use tags with Resource Access Management (RAM) permission policies to manage the access and operation permissions of RAM users on different cloud resources. For more information, see Use tags to enforce access control on resources.
- You can add up to 20 tags to each cloud resource.
- Tag information is not shared across regions. For example, in the China (Shanghai) region, you cannot view tags that are created in the China (Hangzhou) region.
