SAP-C02 Practice Question: Accelerate Workload Migration and Modernization
A company is migrating a large .NET application from Windows Server on-premises to AWS. The application uses a SQL Server database. The company wants to reduce licensing costs by using open-source alternatives where possible. However, the application code heavily uses SQL Server-specific features like CLR integration, linked servers, and T-SQL stored procedures. What is the most cost-effective migration strategy?
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 Server and use Amazon RDS for SQL Server with a license-included option
Replatforming the database to Amazon RDS for SQL Server retains the SQL Server-specific features while reducing operational overhead. Moving to Aurora PostgreSQL or MySQL would require significant code changes. Rehosting on EC2 SQL Server does not reduce licensing costs.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rehost both application and database on Amazon EC2 with SQL Server licenses brought to AWS
Why it's wrong here
License mobility may reduce costs but still requires managing EC2 instances for the database.
- ✗
Refactor the application to use a microservices architecture with separate databases
Why it's wrong here
Refactoring entire application is expensive and not necessary if SQL Server is retained.
- ✓
Rehost the application on Amazon EC2 Windows Server and use Amazon RDS for SQL Server with a license-included option
Why this is correct
Correct. This reduces operational costs and retains SQL Server features.
- ✗
Replatform the database to Amazon Aurora PostgreSQL and rewrite the database code to be compatible
Why it's wrong here
Rewriting database code is costly and time-consuming.
