      Overview

      Tags are key-value pairs provided by Tencent Cloud for easy resource identification. You can use tags to categorize and manage your CVM resources. Tencent Cloud will not use your tags, they are solely used by you to manage your CVM resources.

      Usage Limits

      Note the following limits when using tags:
      Quantity limits: each Tencent Cloud resource allows up to 50 tags.
      Tag key limits:
      Tag keys cannot start with qcloud, tencent, or project.
      A tag key can contain up to 255 characters, including numbers, letters, and +=.@-.
      Tag value limits: a tag value can contain up to 127 characters, including numbers, letters and +=.@-. It can be left empty if necessary.

      Directions and Use Cases

      Use case

      A company has purchased six CVM instances, of which the business group, scope and owners are as follows:
      Instance ID
      Business Group
      Business Scope
      Owner
      ins-abcdef1
      E-commerce
      Marketing campaigns
      John Smith
      ins-abcdef2
      E-commerce
      Marketing campaigns
      Chris
      ins-abcdef3
      Games
      Game A
      Jane Smith
      ins-abcdef4
      Games
      Game B
      Chris
      ins-abcdef5
      Entertainment
      Post-production
      Chris
      ins-abcdef6
      Entertainment
      Post-production
      John Smith
      Taking ins-abcdef1 as an example, we can add the following 3 sets of tags to the instance:
      Tag Key
      Tag Value
      dept
      ecommerce
      business
      mkt
      owner
      John Smith
      Similarly, you can add tag key-value pairs to other instances based on the business group, scope and owners.

      3. In the You have selected 1 resource window that appears, specify the tags as required. As shown in the following figure. For example, you can add three tag key-value pairs to the ins-abcdef1 instance.
      
      
      4. Click OK. A message indicating the edit was successful will be prompted.
