COST03-BP06 Allocate costs based on workload metrics
Allocate the workload's costs by metrics or business outcomes to measure workload cost efficiency. Implement a process to analyze the AWS Cost and Usage Report with Amazon Athena, which can provide insight and charge back capability.
Level of risk exposed if this best practice is not established: Low
Implementation guidance
Cost Optimization is delivering business outcomes at the lowest price point, which can only be achieved by allocating workload costs by workload metrics (measured by workload efficiency). Monitor the defined workload metrics through log files or other application monitoring. Combine this data with the workload costs, which can be obtained by looking at costs with a specific tag value or account ID. It is recommended to perform this analysis at the hourly level. Your efficiency will typically change if you have some static cost components (for example, a backend database running 24/7) with a varying request rate (for example, usage peaks at 9am – 5pm, with few requests at night). Understanding the relationship between the static and variable costs will help you to focus your optimization activities.
Implementation Steps
-
Allocate costs to workload metrics: Using the defined metrics and tagging configured, create a metric that combines the workload output and workload cost. Use the analytics services such as Amazon Athena and QuickSight to create an efficiency dashboard for the overall workload, and any components.
