Tags¶
Tag Management Service (TMS) enables you to use tags on the 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.
Precautions¶
A tag consists of a key and value. You can add only one value for each key.
Each instance can have up to 20 tags.
