What are tags?

A tag is a label that you assign to an AWS resource. Each tag consists of a key and an optional value, both of which you define.

You use tags to categorize your AWS resources in different ways, for example, by purpose, owner, or environment. For example, you could define a set of tags for your account's Amazon EC2 instances, which helps you track each instance's owner and stack level.

Tags don't have any semantic meaning to Amazon EC2 and are interpreted strictly as a string of characters.
