Scenarios

Tag Management Service (TMS) enables you to use tags on the management console to manage resources. TMS works with other cloud services to manage tags. TMS manages tags globally, and other cloud services manage their own tags. If you need to manage a lot of cloud resources, use TMS.

You are advised to set pre-defined tags on the TMS console.
A tag consists of a key and value. You can add only one value for each key.
Each instance can have up to 10 tags.
