AWS tags are used to find the cost distribution of various resources
Explanation:
AWS provides cost allocation tags to categorize and track the AWS costs. When the user applies
tags to his AWS resources, AWS generates a cost allocation report as a comma-separated value
(CSV file. with the usage and costs aggregated by those tags. Each tag will have a key-value and
can be applied to services, such as EC2, S3, RDS, EMR, etc. The maximum size of a tag key isunicode characters.
The following basic restrictions apply to tags:
Maximum key length: 128 Unicode characters
Maximum value length: 256 Unicode characters
Case sensitive
Maximum number of tags per resource: 50; 10 for Amazon S3 buckets
Maximum active tag keys for Billing and Cost Management reports: 500
Reserved prefix—aws:
AWS-generated tag names and values are automatically assigned the aws: prefix, which you cannot assign. User-defined tag names have the prefix user: in the Cost Allocation Report.
Use each key only once for each resource. If you attempt to use the same key twice on the same resource, your request will be rejected.
You cannot tag a resource at the same time you create it. Tagging requires a separate action after the resource is created.
You cannot backdate the application of a tag. This means that tags only start appearing on your cost allocation report after you apply them, and do not appear on earlier reports.
Allowed characters are letters, whitespace, and numbers, plus the following special characters: + – = . _ : /
