Answer: AWS Lambda, Amazon RDS

## Explanation **Correct Answers: B (AWS Lambda) and C (Amazon RDS)** ### Why AWS Lambda? 1. **Least Administrative Effort**: AWS Lambda is a serverless compute service that automatically manages infrastructure, scaling, and patching. This aligns with the requirement for "LEAST administrative effort." 2. **Memory Requirements**: Lambda supports up to 10 GB of memory, easily meeting the 1 GB requirement. 3. **API Gateway Integration**: Lambda integrates seamlessly with Amazon API Gateway for REST APIs. 4. **Storage**: While Lambda has ephemeral storage limits, the 2 GB storage requirement likely refers to the database layer, not compute storage. ### Why Amazon RDS? 1. **Relational Data Format**: The application explicitly requires "data is in a relational format." Amazon RDS is AWS's managed relational database service. 2. **Least Administrative Effort**: RDS handles database administration tasks like backups, patching, and scaling, reducing administrative overhead. 3. **Storage Requirements**: RDS can easily accommodate the 2 GB storage requirement. ### Why NOT the other options? - **A. Amazon EC2**: Requires significant administrative effort for provisioning, scaling, patching, and maintenance. - **D. Amazon DynamoDB**: This is a NoSQL database, not relational, so it doesn't meet the relational format requirement. - **E. Amazon EKS**: Kubernetes requires substantial administrative effort for cluster management, scaling, and maintenance. ### Architecture Overview 1. **API Gateway** → **AWS Lambda** (compute layer with 1GB memory) 2. **AWS Lambda** → **Amazon RDS** (relational database with 2GB+ storage) This serverless architecture minimizes operational overhead while meeting all technical requirements.
