AWS Certified Cloud Practitioner — Question 615

A company needs to host a highly available application in the AWS Cloud. The application runs infrequently for short periods of time.

Which AWS service will meet these requirements with the LEAST amount of operational overhead?

Answer options

• A. Amazon EC2
• B. AWS Fargate
• C. AWS Lambda
• D. Amazon Aurora

Correct answer: C

Explanation

AWS Lambda is a serverless, highly available service that is ideal for short-running, infrequent workloads because users only pay for the compute time consumed, with zero server management required. In contrast, Amazon EC2 and AWS Fargate require more operational management for provisioning and scaling, while Amazon Aurora is a relational database service rather than an application hosting platform.
