Topic 1 Question 335
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?
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.
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.
Replace the containers that run on EC2 instances and the ALB with AWS Lambda functions. Replace the MySQL database with Amazon DynamoDB tables.

- 正解だと思う選択肢: 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).
