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
✓
Rehost the application on Amazon EC2 Windows instances with SQL Server
Rehost (lift-and-shift) involves moving the application as-is to AWS, minimizing changes and time. Option A (Retire) is not appropriate because the application is still needed. Option B (Refactor) requires significant re-architecting. Option D (Replatform) involves some optimization but still requires changes.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Retire the application and replace it with a SaaS solution
Why it's wrong here
Retiring is not appropriate as the application is needed and not being replaced.
- ✗
Refactor the application to use microservices on Amazon ECS
Why it's wrong here
Refactoring requires significant re-architecting, increasing effort and time.
- ✓
Rehost the application on Amazon EC2 Windows instances with SQL Server
Why this is correct
Rehosting moves the application as-is, minimizing effort and time.
- ✗
Replatform the application to use Amazon RDS for SQL Server
Why it's wrong here
Replatforming involves changes like moving to RDS, which still requires effort.

Variation 1. A retail company is migrating its on-premises e-commerce application to AWS. The application currently runs on a single server with a MySQL database. The company wants to minimize operational overhead and improve scalability. Which migration strategy should be used?
easy- A.Re-platform the application to use AWS Elastic Beanstalk and Amazon RDS.
- B.Repurchase a new SaaS-based e-commerce solution.
- C.Refactor the application as microservices on Amazon ECS with Amazon Aurora Serverless.
- ✓ D.Rehost the application on Amazon EC2 and use Amazon RDS for MySQL.
Why D: (Rehost) is the best migration strategy for this scenario because it involves lifting and shifting the application to Amazon EC2 with minimal changes, and using Amazon RDS for MySQL reduces operational overhead for database management. Rehosting is the fastest approach and aligns with the goal of minimizing operational overhead while improving scalability through managed services. Option A (Re-platform) would require modifications to use Elastic Beanstalk, increasing effort. Option B (Repurchase) involves switching to a new SaaS solution, which is not a migration of the existing application. Option C (Refactor) requires significant development to convert to microservices, which is high effort and not necessary for the stated goals.
