A company runs its application on an Oracle database. The company plans to quickly migrate to AWS because of limited resources for the database, backup administration, and data center maintenance. The application uses third-party database features that require privileged access.

A
Migrate the database to Amazon RDS for Oracle. Replace third-party features with cloud services.
B
Migrate the database to Amazon RDS Custom for Oracle. Customize the database settings to support third-party features.
C
Migrate the database to an Amazon EC2 Amazon Machine Image (AMI) for Oracle. Customize the database settings to support third-party features.
D
Migrate the database to Amazon RDS for PostgreSQL by rewriting the application code to remove dependency on Oracle APEX.

Explanation
Correct Answer: B - Migrate the database to Amazon RDS Custom for Oracle. Customize the database settings to support third-party features.
Why this is the most cost-effective solution:
-
RDS Custom for Oracle is specifically designed for scenarios where:
- Applications require privileged access to the database
- Third-party features or customizations are needed
- You need to maintain compatibility with existing Oracle features
-
Cost-effectiveness factors:
- Reduced administrative overhead: RDS Custom still provides managed database services (automated backups, patching, monitoring) while allowing customization
- No application rewrite: The company can keep their existing application code
- Faster migration: No need to replace third-party features or rewrite application code
- Balanced approach: Combines managed service benefits with customization flexibility
Why other options are less cost-effective:
-
Option A (RDS for Oracle): While RDS for Oracle is managed, it doesn't allow privileged access or support for third-party features that require customization. Replacing third-party features with cloud services would require significant development effort and testing.
-
Option C (EC2 AMI for Oracle): This requires full self-management of the database (backups, patching, maintenance), which contradicts the company's goal of reducing database administration overhead. While it allows customization, it's not cost-effective due to high operational overhead.
-
Option D (RDS for PostgreSQL): Rewriting application code to remove Oracle dependencies is expensive, time-consuming, and risky. This approach has high migration costs and requires extensive testing.
Key considerations:
- The company wants to migrate quickly with limited resources
- They need to maintain third-party database features
- They want to reduce database administration and maintenance burden
- RDS Custom provides the right balance between managed services and customization capabilities
AWS Service Context:
- Amazon RDS Custom: A managed database service that provides automated backups, software patching, and monitoring while allowing access to the underlying OS and database for customizations
- Amazon RDS: Fully managed service but with restrictions on OS and database access
- Amazon EC2: Infrastructure as a Service requiring full self-management of the database stack
