Overview

TMS allows you to easily classify and search for your resources with tags. You can manage multiple tags in a list view.

For example, you can specify a region to view all resource tags and predefined tags or you can add a tag to multiple resources at a time. You can add a tag to 500 resources at most each time.

This section describes how to query resources by tag, create tag keys, add a tag to multiple cloud resources, and update, modify, or delete resource tags.
