Managing GaussDB Tags

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. Other cloud services manage only their own tags.

You can use unified tags to manage various resources and use custom tags to define different DB instance categories. This section describes how to edit and delete tags.

Precautions

• You are advised to configure predefined tags on the TMS console.
• A tag consists of a key and value. You can add only one value for each key.
• A maximum of 20 tags can be added for an instance.
