AWS Certified Cloud Practitioner — Question 431

A company is running and managing its own Docker environment on Amazon EC2 instances. The company wants an alternative to help manage cluster size, scheduling, and environment maintenance.

Which AWS service meets these requirements?

Answer options

• A. AWS Lambda
• B. Amazon RDS
• C. AWS Fargate
• D. Amazon Athena

Correct answer: C

Explanation

AWS Fargate is a serverless compute engine for containers that eliminates the need to provision, configure, or scale virtual machines, directly addressing the company's need for automated cluster management and maintenance. AWS Lambda is designed for event-driven functions rather than standard Docker cluster management, while Amazon RDS and Amazon Athena are database and query services, respectively.
