About This Architecture

Multi-AZ Elastic Beanstalk architecture with Auto Scaling Groups spanning two availability zones for fault tolerance and load distribution. Traffic flows from the Internet Gateway through an Elastic Load Balancer to EC2 instances running custom AMIs, which connect to a Multi-AZ RDS MySQL database with automatic failover. CloudWatch Alarms trigger CPU-based scaling events and send notifications via SNS, while IAM roles enforce least-privilege access across Beanstalk and EC2 resources. This pattern demonstrates production-grade resilience, eliminating single points of failure and enabling seamless scaling during traffic spikes.

How do I design a highly available web application on AWS Elastic Beanstalk across multiple availability zones?

This diagram shows a production-grade Elastic Beanstalk architecture spanning two AZs with Auto Scaling Groups, an Elastic Load Balancer, and RDS Multi-AZ for automatic database failover. CloudWatch Alarms monitor CPU utilization and trigger scaling events, while SNS notifications alert operators, ensuring your application remains available during failures and traffic surges.
