SAP-C02 Question 539
Select 3A retail company is planning to migrate its on-premises e-commerce platform to AWS. The application consists of a monolithic architecture with tightly coupled components, including a web server, application server, and database. The company wants to modernize the application during migration to improve scalability, operational efficiency, and cost-effectiveness. Which of the following approaches should you recommend to achieve these goals?
- A
Refactor the application into microservices using AWS Lambda and Amazon API Gateway.
- B
Lift and shift the application to Amazon EC2 instances using AWS Application Migration Service.
- C
Migrate the database to Amazon RDS and decouple it from the application logic.
- D
Use Amazon ECS or Amazon EKS to containerize the application components and manage them as microservices.
- E
Migrate the entire application as-is to Amazon S3 and use it as a static website hosting solution.
Show answer and explanation
Correct answers: A, C, D
Explanation
To accelerate workload migration and modernization, you should aim to decouple and refactor the application into a microservices architecture, migrate databases to managed services like Amazon RDS, and leverage containerization tools like Amazon ECS or EKS for better scalability and operational efficiency. These approaches align with AWS best practices for modernizing workloads during migration.
- A. Correct.
Refactoring the application into microservices using AWS Lambda and Amazon API Gateway is a recommended approach for modernization as it enables scalability, operational efficiency, and cost-effectiveness. However, this requires additional development effort.
- B. Incorrect.
A lift-and-shift approach using AWS Application Migration Service does not modernize the application. It simply replicates the on-premises setup on AWS without addressing scalability or efficiency.
- C. Correct.
Migrating the database to Amazon RDS and decoupling it from the application enables better management, scalability, and high availability, which aligns with modernization goals.
- D. Correct.
Using Amazon ECS or Amazon EKS to containerize the application components allows for better resource utilization, scalability, and management of microservices, which is a key aspect of modernization.
- E. Incorrect.
Migrating the application as-is to Amazon S3 is not feasible for a monolithic e-commerce application with dynamic server-side processing. This option is only suitable for hosting static websites.
