About This Architecture

Multi-AZ web application architecture integrates AWS Cognito User Pool with Application Load Balancer for centralized authentication across us-east-1a and us-east-1b availability zones. Users authenticate through Cognito before ALB routes traffic to EC2 t3.medium instances in private subnets (10.0.2.0/24, 10.0.4.0/24) within VPC 10.0.0.0/16. This pattern offloads identity management to a managed service, eliminating custom authentication code while ensuring high availability through dual-AZ deployment. Fork this diagram on Diagrams.so to customize subnet ranges, add RDS backend tiers, or integrate with API Gateway for serverless components. Ideal for teams migrating from session-based auth to OAuth 2.0 flows with JWT token validation at the load balancer layer.
