[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A company runs an application in an Auto Scaling group of Amazon EC2 instances behind an Application Load Balancer (ALB). The EC2 instances run Docker containers that make requests to a MySQL database that runs on separate EC2 instances.

A DevOps engineer needs to update the application to use a serverless architecture.

Which solution will meet this requirement with the FEWEST changes?

A. Replace the containers that run on EC2 instances and the ALB with AWS Lambda functions. Replace the MySQL database with an Amazon Aurora Serverless v2 database that is compatible with MySQL.
B. Replace the containers that run on EC2 instances with AWS Fargate. Replace the MySQL database with an Amazon Aurora Serverless v2 database that is compatible with MySQL.
C. Replace the containers that run on EC2 instances and the ALB with AWS Lambda functions. Replace the MySQL database with Amazon DynamoDB tables.
D. Replace the containers that run on EC2 instances with AWS Fargate. Replace the MySQL database with Amazon DynamoDB tables.

Selected Answer: A

Replace EC2 + ALB with AWS Lambda → Moves compute to serverless. Replace MySQL with Aurora Serverless v2 (MySQL-compatible) → Keeps compatibility with MySQL, meaning minimal code/database query changes. ✅ Best choice because it fully transitions to serverless (compute + database) with the least disruption to existing code. It offers a fully serverless solution with minimum code changes, since: Lambda can take over the logic in containers. Aurora Serverless v2 provides MySQL compatibility, so the data layer is minimally impacted.

Selected Answer: B

"B" is the most easy-to-implement option - as the question asks. The rest options require moving from SQL to NoSQL (which requires multiple code changes) and/or moving from Docker containers to Lambda (which requires multiple code changes).
