Concepts
Cost allocation tags are labels that you can assign to AWS resources to categorize and track your AWS costs. Tags consist of a key and a value, for example, {"Environment": "Production"} or {"Project": "ProjectX"}. You can activate these tags in the AWS Billing and Cost Management console, and they can help you to organize your resources by project, department, application, or any other system that fits your business.
There are two types of cost allocation tags:
- AWS-generated tags – These are automatically created by AWS services. For example,
aws:createdByholds the IAM entity that created the resource. - User-defined tags – These are created by the user to organize resources in customized ways.
Example of User-defined tag activation:
To activate user-defined tags for cost allocation, you would do the following in the AWS Management Console:
- Navigate to the Billing and Cost Management Dashboard.
- Click on “Cost Allocation Tags” under the “Billing” section.
- Select the tags you want to activate, then click “Activate”.
Once activated, these tags will appear in your cost reports, allowing you to break down your costs by the tag keys and values that you have defined, which can be very useful when analyzing your AWS bill.
Multi-Account Billing
Multi-account billing is another vital feature for managing AWS costs, especially for organizations that operate multiple AWS accounts. AWS Organizations allows you to consolidate billing for multiple AWS accounts, simplifying the cost management process. Centralized billing has several advantages:
- Consolidated Payments: One bill for all accounts.
- Volume Discounts: Combined usage across accounts can help you qualify for volume discounts.
- Simplified Tracking: Track the charges and usage across different accounts in a single place.
Additionally, AWS’ Consolidated Billing feature allows you to use a single payment method for all accounts in your organization, which streamlines the payment process.
AWS Organizations also support features like:
- Service Control Policies (SCPs): SCPs allow you to define permissions for member accounts, which can also help in cost control by restricting access to expensive AWS services.
- Automated Account Creation: Quickly create new accounts in your organization, which inherit the organization’s settings, including consolidated billing.
Example of Cost Reporting with multiple accounts:
Each AWS account in an organization can be assigned an Account ID. When you view the cost reports, you can typically see the breakdown of costs by the Account ID, which makes it easier to track where the expenses are coming from. AWS Cost Explorer further enables visualization and analysis of costs at an even more granular level within each account.
To sum up, cost allocation tags and multi-account billing are crucial features for managing your AWS costs effectively. Understanding how to implement and make the most of these features is a valuable aspect of an AWS Certified Solutions Architect’s skill set, enabling better decision-making, budget control, and financial governance in the cloud environment.
