Concepts
Amazon Web Services (AWS) provides a suite of cost management tools that help users monitor and control their AWS spending. These tools enable customers to get a clear understanding of their costs and usage, forecast future costs, and establish budgets and alerts. Understanding how to leverage these tools is essential for any individual aiming to pass the AWS Certified Solutions Architect – Associate exam. Let’s delve into some of the primary AWS cost management tools and their appropriate use cases.
AWS Cost Explorer
AWS Cost Explorer is an intuitive tool that enables users to visualize their AWS costs and usage patterns over time. With Cost Explorer, you can analyze your costs from different perspectives, such as by service, linked account, region, or usage type.
Use Case: Identifying Trends in Spending
For instance, a company might want to identify the services contributing to the highest costs. Cost Explorer can help by allowing them to generate reports that break down costs by service. The company can then pinpoint the top services and decide where to optimize their consumption.
Use Case: Reserved Instance Optimization
Another common use case involves analyzing reserved instances (RIs). Cost Explorer can show RI utilization and coverage, helping organizations decide whether to purchase additional RIs, modify existing ones, or switch to Savings Plans based on their usage patterns.
AWS Budgets
AWS Budgets allows users to set custom budgets to monitor their AWS cost and usage. It provides alerts when the costs or usage exceed (or are forecasted to exceed) the budgeted amount. AWS Budgets can also track RI and Savings Plans utilization and coverage.
Use Case: Controlling Monthly Spending
A business may set a budget to control its monthly expenditure on AWS services. AWS Budgets would alert the finance team whenever their costs are projected to exceed this budget, allowing them to take proactive measures to reduce spending or investigate unexpected charges.
Use Case: Departmental Budgeting
In a large organization with multiple departments using AWS, each department can have its budget based on their allocated resources or projects. AWS Budgets will help ensure that each department stays within its financial boundaries.
AWS Cost and Usage Report
The AWS Cost and Usage Report (CUR) is the most comprehensive tool for accessing detailed information about your AWS costs and usage. It delivers a set of CSV files that contain hourly, daily, or monthly aggregated data.
Use Case: Detailed Cost Analysis and Rebilling
For granular accounting or rebilling purposes, an enterprise might require highly detailed reports showing every API call or service used. The Cost and Usage Report can be ingested into an analytics tool, enabling deep dives into the data and precise chargebacks to internal or external customers.
Use Case: Data Transfer Analysis
A company can utilize the Cost and Usage Report to analyze data transfer costs across different regions and services, understanding cross-region transfer costs that may be optimized by architectural changes or by using different services like AWS CloudFront.
In the context of the AWS Certified Solutions Architect – Associate exam, candidates should understand when and how to use these tools effectively for cost optimization. They should know the benefits and limitations of each tool and be able to recommend appropriate cost management strategies in various scenarios.
To demonstrate these capabilities in an exam scenario, for instance, a question may be posed about a customer who needs to reduce their AWS bill. The candidate would need to analyze the situation and might suggest using AWS Cost Explorer to identify the highest costs and then employ AWS Budgets to set a reduced spending target, with alerts to ensure costs stay on track.
