Managing Costs in AWS
Managing costs is a critical aspect of managing resources in cloud platforms like Amazon Web Services (AWS). AWS provides various features and tools to help users understand, manage, and optimize costs. In this article, we’ll focus on features such as cost allocation tags and multi-account billing. This knowledge is highly beneficial for those studying for the “AWS Certified Solutions Architect – Associate (SAA-C03)” exam.
1. Cost Allocation Tags
AWS allows users to assign metadata to their AWS resources in the form of tags. These User-Defined Cost Allocation Tags enable the tracking of AWS costs, making it easier to see the costs associated with different projects, departments, or other categories that make sense for your business.
- Activation of User-Defined Tags For Cost Allocation: AWS doesn’t automatically categorize costs according to your user-defined tags. You must activate them in the AWS Billing and Cost Management dashboard to include them in the AWS Cost and Usage report.
- Use Case for Cost Allocation Tags: If your organization has different departments using the same AWS account, you can associate the resources each department uses with a unique tag. At the end of the month, you can track costs by each tag (for example, by ‘department1’, ‘department2’, etc.), streamlining your cost allocation process.
2. AWSCostExplorer API
This detailed cost and usage metrics API service allows users to programmatically query cost and usage data. You can use it to analyze, visualize, and understand your expenditure.
- Example Use Case: If you wish to provide cost data to a custom application dashboard, you can use the AWSCostExplorer API to query AWS for detailed cost data.
3. Multi-Account Billing
AWS Organizations’ consolidated billing feature lets you combine usage from multiple AWS accounts into a single payment method. Essentially, all the resources used by ‘member’ accounts contribute to reaching AWS usage volume tiers, reducing overall costs.
- Benefits of Consolidated Billing in AWS: It can help your organization significantly cut costs. You can receive one bill for multiple accounts, which allows you to track each account’s costs while maximizing volume discounts across those accounts.
- Example: If you have three accounts each storing 5000GB in Amazon S3, instead of being billed separately at a higher rate, the accounts are combined under consolidated billing. This means you’ll be billed for the 15000GB at a lower rate due to the discount at higher usage tiers.
To conclude, understanding and utilizing AWS cost management services like cost allocation tags and multi-account billing are crucial in managing your AWS resources efficiently. These strategies not only help in tracking your AWS costs but also in optimizing them, making them an essential area of knowledge for AWS Certified Solutions Architect – Associate (SAA-C03) exam candidates. It is vital to consider these features in your cost management strategies, and to leverage AWS’s cost management tools to optimize your AWS resource usage and associated costs.
