A tag is a key-value pair that consists of a tag key and tag value. Tags are used to identify resources. You can use tags to group and manage cloud computers. Tags help you search for and perform batch operations on cloud computers with ease.
Background
As the number of cloud computers increases in an enterprise, cloud computers become difficult to manage. In this case, you can bind tags to cloud computers to streamline management. Then, you can filter cloud computers by tag to batch perform operations in subsequent O&M. You can bind up to 20 tags to a cloud computer and specify the tag key and value for each tag based on your business requirements. The following table provides examples on tag keys and values from different dimensions.
Dimension | Tag key | Tag value |
Organization | department | The department name. Examples: MD and FD. |
Business | project | The project name. Examples: projectA and projectB. |
Job position | position | The position name. Examples: designer and programmer. |
Take note of the following items when you use tags:
Each tag consists of a tag key and tag value. The tag key must be unique globally. For example, you have bound the
department:MDtag to a cloud computer. If you want to add another tagdepartment:FDto the cloud computer, the previous tag becomes invalid and are unbound from it.After a tag is unbound from a cloud computer and you no longer bind the tag to other resources, the tag is automatically deleted.
Tags in a region are unique.
