About This Architecture

Smart Parking System on AWS uses a three-tier, multi-AZ architecture spanning us-east-1a and us-east-1b with CloudFront CDN, WAF, and Application Load Balancers protecting the presentation layer. Entry and exit flow EC2 instances (t3.medium) route to Spring Boot backends on ECS Fargate, while Lambda functions handle ticket generation, slot allocation, and billing independently. RDS MySQL primary-standby replication manages slots and tickets across AZs, with DynamoDB session stores ensuring low-latency user state. This architecture delivers high availability, automatic failover, and elastic scaling for peak parking demand. Fork and customize this diagram on Diagrams.so to adapt subnet ranges, instance types, or add additional Lambda workflows for your parking operations.
