      Overview

      Tag is a key-value pair provided by Tencent Cloud which is used to identify resources on the cloud.
      You can use tags to classify CKafka resources based on various factors such as service, usage, and person in charge. With tags, you can quickly filter out the corresponding resources. The key-value pair of the tag does not mean anything to Tencent Cloud semantically and will be parsed and matched strictly according to the string.

      Case background

      A company has 10 CKafka instances on Tencent Cloud, which are owned by three departments: Ecommerce, Game, and Entertainment. The instances are used for services such as marketing, game A, game B, and post-production. The OPS owners of the three departments are John, Jane, and Harry, respectively.

      Setting tags

      To facilitate management, the company categorizes its CKafka resources with tags and defines the following tag key-value pairs.

      Tag Value

      Ecommerce, Game, and Entertainment
      Business
      Marketing, Game A, Game B, and Post-production

      Bind the tag key-value pairs to CKafka. The relation between resources and the tag key-value pairs is shown in the table below.
