A tag is a metadata label that either you or AWS
assigns to an AWS resource. Each tag consists of a key
and a value. For tags that you assign, you define the key
and the value. For example, you might define the key as purpose and the value
as test for a resource.
Tags help you do the following:
-
Identify and organize your AWS resources. Many AWS services support tagging, so you can assign the same tag to resources from different services to indicate that the resources are related.
-
Control access to your AWS resources. For more information, see Controlling Access Using Tags in the IAM User Guide.
Tagging restrictions
The following basic restrictions apply to tags on AWS FIS resources:

Maximum number of tags that you can assign to a resource: 50

Maximum value length: 256 Unicode characters
-
Valid characters for keys and values: a-z, A-Z, 0-9, space, and the following characters: _ . : / = + - and @

You cannot use
aws:as a prefix for keys, because it's reserved for AWS use
