Answer: Use Amazon S3 to host static content. Use Amazon Elastic Container Service (Amazon ECS) with AWS Fargate for compute power. Use a managed Amazon RDS cluster for the database.

## Explanation **Option A is correct** because it provides the most cost-effective and simplified deployment solution: 1. **Amazon S3 for static content**: S3 is ideal for hosting static websites as it's highly scalable, cost-effective, and requires no server management. 2. **Amazon ECS with AWS Fargate**: This is a serverless compute engine for containers that eliminates the need to manage EC2 instances, reducing operational overhead and costs. Fargate automatically scales and manages the underlying infrastructure. 3. **Managed Amazon RDS cluster**: RDS provides a fully managed relational database service, reducing operational complexity. **Why other options are incorrect**: - **Option B**: Uses CloudFront for static content hosting, which is primarily a CDN service, not a hosting service. While CloudFront can be used with S3 origin, it's not a hosting solution by itself. Also uses EC2 instances with ECS, which requires more operational management than Fargate. - **Option C**: Uses Amazon EKS with Fargate, which is more complex than ECS for simple container orchestration needs. ECS is simpler and more cost-effective for most use cases. - **Option D**: Uses EC2 Reserved Instances for static content, which is inefficient and costly compared to S3. Also uses EC2 instances with EKS, which requires significant operational management. The key requirements are **simplify deployment** and **reduce operational costs**. Option A achieves both by using serverless/managed services (S3, Fargate, RDS) that minimize operational overhead and provide cost optimization through pay-as-you-go pricing.
