Concepts
Cost allocation tags enable users to assign metadata to AWS resources, which can then be used to organize and track AWS costs. There are two types of tags:
- AWS-Generated Tags: These tags are automatically created by AWS, such as the aws:createdBy tag, which shows which user or service created the resource.
- User-Defined Tags: These are created by the user to categorize resources in ways that are meaningful to their business.
Tags can be used for various purposes such as detailed cost tracking, automation, managing resource permissions, and more. To implement cost allocation tags, follow these steps:
-
Activate Cost Allocation Tags:
Navigate to the AWS Cost Management console, select ‘Cost Allocation Tags,’ and then choose ‘Activate’ next to the tags you wish to use.
-
Tag Your Resources:
– For an Amazon EC2 instance, you can tag the resource via the AWS Management Console or using the AWS CLI.
aws ec2 create-tags –resources i-1234567890abcdef0 –tags Key=Environment,Value=Production
– Repeat the tagging process for other resources like Amazon S3 buckets, Amazon RDS instances, etc.
-
Use Tags for Cost Allocation:
In the AWS Cost Explorer or Billing Dashboard, you can filter by tags to see detailed cost breakdowns. This detailed view helps you understand and manage costs aligned with specific projects, environments, or organizational structures.
For example, if an organization wants to track the costs of resources used by different departments, they can apply user-defined tags such as Department: Marketing and Department: Finance to their respective resources.
Multi-Account Billing
AWS multi-account billing is a feature designed to simplify the payment process for organizations that use multiple AWS accounts. With this feature, users can consolidate billing and payment for multiple AWS accounts within an organization using AWS Organizations, enabling centralized control over budgets and expenditures.
The main components include:
- Master (Payer) Account: This is the central account that pays for all the charges incurred by the member accounts. It receives a single bill covering all accounts.
- Member (Linked) Accounts: These are the individual accounts that are part of the organization and have their costs rolled up to the master account.
- Consolidated Billing: Combines the usage from all accounts to help you get volume discounts since pricing is often tiered based on usage.
- Cost Explorer: Can be used at the master account level to view and analyze costs across multiple accounts.
Enabling multi-account billing involves setting up AWS Organizations and then inviting or creating new member accounts. After setup, the master account can view combined usage and take advantage of consolidated billing features such as volume discounts.
For example, suppose your organization has three AWS accounts representing development, testing, and production. By setting up multi-account billing, all costs from these accounts are combined, allowing the organization to benefit from consolidated payment methods and often lower prices due to aggregate usage discounts.
To summarize, both cost allocation tags and multi-account billing are potent features that help AWS customers manage and optimize their costs. They are instrumental for solutions architects who need to design cost-effective cloud solutions. Thorough knowledge and understanding of these services are, therefore, highly beneficial and recommended for candidates preparing for the AWS Certified Solutions Architect – Associate exam.

This blog post was really helpful in understanding AWS cost management service features. Thanks!
Cost allocation tags have been game-changers for us in tracking expenses by project.
Can someone explain how multi-account billing works in AWS?
Could we discuss best practices for setting up cost allocation tags?
Appreciate the breakdown of cost management features!
Implementing these features has saved us both time and money.
I found the section on AWS Organizations and consolidating billing very useful.
The way AWS handles cost allocation tags can be a bit confusing initially.
