How can I tag my AWS resources to divide up my bill by cost center or project?

Tags are key-value pairs that allow you to organize your AWS resources into groups. You can use tags to:

• Visualize information about tagged resources in one place, in conjunction with Resource Groups.
• View billing information using Cost Explorer and the AWS Cost and Usage report.
• Send notifications about spending limits using AWS Budgets.

Use logical groupings of your resources that make sense for your infrastructure or business. For example, you could organize your resources by:

• Project
• Cost center
• Development environment
• Application
• Department

Not all resources support tags. For a list of resources that can be tagged, see User-Defined Cost Allocation Tags.

After you know what you want to tag, implement a new tagging strategy.
