AWS Certified Cloud Practitioner — Question 505

A company must compare the cost of running a MySQL database on an Amazon EC2 instance and Amazon RDS DB instance.

Which AWS service or tool should the company use?

Answer options

• A. AWS Budgets
• B. AWS Control Tower
• C. AWS Outposts
• D. AWS Pricing Calculator

Correct answer: D

Explanation

The AWS Pricing Calculator allows users to estimate the cost of AWS services, enabling a side-by-side cost comparison between self-hosting MySQL on Amazon EC2 and using the managed Amazon RDS service. AWS Budgets is used to set cost alerts and track spending against a budget, while AWS Control Tower helps set up and govern secure multi-account environments. AWS Outposts is designed for running AWS infrastructure on-premises, making it irrelevant for this cloud-based cost comparison.
