You can classify Server Load Balancer (SLB) instances by using tags.

Each tag consists of a key and a value. Before you use tags, note the following limits:

  • A tag cannot exist on its own and must be associated with an SLB instance.
  • Up to 10 tags can be associated with an SLB instance.
  • The key of each tag associated with an instance must be unique. Tags with the same key will be overwritten.
  • Tags cannot be used across regions and are region-specific resources. For example, tags that belong to the China (Hangzhou) region are invisible to the China (Shanghai) region.
