A company is deploying a web application that consists of a web tier serving static content, an application tier for dynamic processing, and a database tier for data persistence. The application needs to handle unpredictable traffic and maintain high availability. Which of the following architectural designs is MOST suitable for meeting these requirements?
Utilize Amazon CloudFront for the web tier, AWS Lambda for the application tier, and Amazon DynamoDB for the database tier to ensure serverless scalability.
Use Amazon S3 to serve static content, Auto Scaling groups for the application tier, and Amazon RDS with Multi-AZ deployment for data persistence.
Deploy a single Amazon EC2 instance in each tier including the web, application, and database tiers for simpler manageability and cost savings.
Use Amazon EC2 with Elastic Load Balancing for all tiers, and handle data persistence by replicating data between multiple EC2 instances in different regions.
