SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a monolithic application to AWS. The application currently runs on a single on-premises server with a MySQL database. The company wants to reduce operational overhead and improve scalability. Which combination of AWS services should the company use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use AWS Elastic Beanstalk to deploy the application and Amazon RDS for MySQL as the database.
AWS Elastic Beanstalk automates application deployment, capacity provisioning, load balancing, and scaling, reducing operational overhead. Amazon RDS for MySQL manages the database, providing scalability and reducing administrative tasks. Option A is incorrect because while ECS with Fargate and Aurora Serverless can reduce overhead, containerizing a monolithic application requires refactoring and may not be straightforward; Elastic Beanstalk is more suitable for a lift-and-shift migration of a monolithic app. Option B is incorrect because DynamoDB is a NoSQL database and not compatible with the existing MySQL database without significant schema changes, and AWS Lambda is event-driven and not ideal for a monolithic application. Option C is incorrect because running the application on EC2 instances still requires manual management of operating system patches, scaling, and availability, which does not reduce operational overhead as much as Elastic Beanstalk.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Containerize the application and run on Amazon ECS with AWS Fargate, and use Amazon Aurora Serverless for MySQL.
Why it's wrong here
Aurora Serverless may not be fully compatible and containerization adds complexity.
- ✗
Migrate the database to Amazon DynamoDB and host the application on AWS Lambda.
Why it's wrong here
Requires significant code changes.
- ✗
Host the application on Amazon EC2 and use Amazon RDS for MySQL.
Why it's wrong here
Still requires managing EC2 instances.
- ✓
Use AWS Elastic Beanstalk to deploy the application and Amazon RDS for MySQL as the database.
Why this is correct
Elastic Beanstalk manages the environment, RDS reduces DB management overhead.
