Anti-DDoS Pro allows you to manage the tags of an instance. You can use tags to mark instances and manage instances with the same tag simultaneously.

Background information

Each tag is a key-value pair. Tags have the following limits:
  • You can attach up to 20 tags to an instance.
  • The key of each tag attached to an instance must be unique. The tag value of a new tag key overwrites the tag value of an existing tag key.
  • Each tag must be attached to at least one instance.
