Introducing AWS Cost Categories
With AWS Cost Categories (GA), you can now categorize your cost and usage information precisely to your organizational structure and cost allocation needs such as teams, cost centers, geography, applications, and more. Using Cost Categories, you can create these unique categories and then write rules on which costs belong to each group. After defining your unique category, you can view, track, and optimize costs using Cost Categories in the AWS Cost Management suite of products such as AWS Cost Explorer, AWS Budgets, and AWS Cost and Usage Report (‘CUR’).
