Which AWS Service Monitors Ecommerce Website Costs Against a Budget?
A company plans to launch an ecommerce website that contains many images for a product catalog. The company wants to keep the cost of running the website within a specific budget. Which AWS service or tool should the company use to monitor the ongoing costs of the website?
Community Votes
67% of anonymous learners picked answer A. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The question tests whether you can separate cost-management tooling from deployment and image-pipeline services; the trap is picking a service whose name includes 'Image' because the site stores product images.
AWS Cost Explorer is the service for analyzing and monitoring AWS spend, so it is the right tool when an ecommerce site must stay within a cost budget. The page confirms A and explains why SDKs, EC2 Image Builder, and CloudFormation do not provide cost monitoring.
The most common wrong answer is C, EC2 Image Builder, because the scenario mentions many product images, but EC2 Image Builder creates VM or container images and does not monitor ongoing AWS costs.

Expert Analysis
Why the Answer Is Correct
AWS Cost Explorer is the only listed service that analyzes and forecasts AWS spending, which directly matches the requirement to monitor ongoing costs for an ecommerce website. It can break down costs by service, account, or tag, so the company can see whether S3 storage for product images, compute, and other resources are staying within the intended budget. Cost Explorer also supports historical trends and forecasting, which helps the company act before costs exceed the budget. Therefore, option A is the appropriate AWS service or tool among the choices given.Why the Other Options Are Wrong
AWS SDKs are developer libraries for calling AWS APIs from application code; they do not provide a built-in cost monitoring dashboard or budget view. EC2 Image Builder automates the creation and maintenance of VM or container images, and the presence of ecommerce product images in the scenario is a deliberate distractor rather than a cost-control use case. AWS CloudFormation provisions infrastructure as code and can deploy the website's resources, but it does not monitor ongoing spend or compare costs against a budget. None of these options provide the cost visibility that the company needs.Community Comment Notes
SussyBoi842 put it simply: "Only option that monitor's cost to my knowledge is A". Another learner, 2682f50, expanded that Cost Explorer supports cost analysis, budget monitoring, and forecasting for resources such as S3 image storage and EC2. Nikmah's note on EC2 Image Builder is a useful caution: it automates VM or container image creation, which explains why the "images" wording can mislead. d00b229 also selected A, and that consensus aligns with the service capabilities described in AWS documentation.Official Reference
Exam Strategy
When a question uses verbs such as monitor, track, forecast, or stay within budget, map those verbs to the AWS cost-management category first. Then eliminate services that deploy infrastructure or build images, because they solve operational tasks rather than financial visibility.
Frequently Asked Questions
Why is AWS Cost Explorer right instead of EC2 Image Builder for this ecommerce site?
Cost Explorer analyzes and forecasts AWS spend, while EC2 Image Builder automates VM or container image creation and has no cost-monitoring capability. The product images in the scenario are a distractor.
Does AWS CloudFormation help monitor ongoing website costs?
No. CloudFormation provisions infrastructure as code; it does not provide cost analysis, budget tracking, or spend forecasting.
