Key Concepts
- Enforce tags usage: ensure that your users create and attach resource tags to the AWS resources they plan to deploy / are using.
- Validate tags values: verify whether the tag values your users define are consistent with your company’s tagging strategies.
How long can an AWS tag be?
255 characters
The maximum length of a tag value is 255 characters. Tag keys and values are case sensitive. The aws: prefix is reserved for AWS use; you cannot add, edit, or delete tags whose key begins with aws: .
Tag keys and values are case-sensitive. Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for AWS use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
What is an AWS tag What are tags used for?
You can assign metadata to your AWS resources in the form of tags. Each tag is a label consisting of a user-defined key and value. Tags can help you manage, identify, organize, search for, and filter resources. You can create tags to categorize resources by purpose, owner, environment, or other criteria.
How do I use AWS tags?
If you’re using the Amazon EC2 console, you can apply tags to resources by using the Tags tab on the relevant resource screen, or you can use the Tags screen. Some resource screens enable you to specify tags for a resource when you create the resource; for example, a tag with a key of Name and a value that you specify.
Is AWS config expensive?
AWS Config costs money, although not a lot at $0.003/resource/month. Where it does get expensive is if you start using AWS Config Rules. Those rules will cost you $2/rule/month/region with some bulk discounts. There are 82 managed AWS Config Rules (so not including ones you create yourself).
What does AWS SSM stand for?
AWS Systems Manager
AWS Systems Manager (formerly known as SSM) is an AWS service that you can use to view and control your infrastructure on AWS. Using the Systems Manager console, you can view operational data from multiple AWS services and automate operational tasks across your AWS resources.

How are AWS resource tags used in AWS?
Tags can also control access to AWS resources, be applied to IAM users and roles, and locate AWS resources, either via AWS APIs or directly in the AWS console. Customers asked us how you can ensure teams consistently create and apply the resources tags based on the tagging strategy.
How are cost allocation tags used in AWS?
Cost allocation tags can indicate which resources are contributing to costs, but deleting or deactivating resources doesn’t always reduce costs. For example, snapshot data that is referenced by another snapshot is preserved, even if the snapshot that contains the original data is deleted.
What does it mean to deny access to a tag in AWS?
Denying access to DescribeTags doesn’t automatically deny access to tags returned by other APIs. As a best practice, we recommend that you do not include sensitive data in your 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.
