AWS Three-Tier Web Application

This AWS architecture diagram separates a public web application into edge, web, application and data tiers. Internet traffic reaches Amazon CloudFront, then an Application Load Balancer and an EC2 web tier. The web tier calls an EC2 application tier, which stores relational data in Amazon RDS and files in Amazon S3. The drawing gives teams a compact way to discuss traffic flow and responsibility boundaries before adding more detailed networking controls.
