AWS Three-Tier Web Application

This AWS three-tier web application diagram shows a straightforward application path from internet users through an Application Load Balancer to an EC2 application tier. The application reads or writes through RDS Multi-AZ and ElastiCache, serves static assets from S3, and reports operational data to CloudWatch. It is useful for design reviews and documentation when the audience needs to see the AWS services and their roles without a detailed VPC or security-group diagram.
