Which AWS service analyzes your existing resource configurations and utilization metrics to recommend optimal instance types for cost savings and better performance?
Show answer and explanation
Answer: B
AWS Compute Optimizer applies machine learning to the utilization metrics your resources generate and then recommends rightsized EC2 instance types, EBS volume configurations, Lambda settings, and Fargate configurations that meet each workload's needs more efficiently.
Cost Explorer visualizes spend, Trusted Advisor issues broad best-practice checks, and Budgets guards spending thresholds — none inspect utilization patterns to pick instance types.
Why the other options are wrong
- A. Cost Explorer charts and forecasts costs; it reads billing data and knows nothing about a resource's utilization profile.
- C. Trusted Advisor runs fixed best-practice checks across categories; it does not perform instance-type analysis from utilization metrics.
- D. Budgets watches cost against thresholds and sends alerts, offering no rightsizing recommendations.
