About This Architecture

Multi-AZ booking platform architecture spanning us-east-1a and us-east-1b with WAF, CloudFront CDN, and Application Load Balancers protecting Node.js/Express API servers. Traffic flows from customers and providers through WAF to CloudFront, then to ALB, routing to stateless API servers handling JWT authentication, booking logic, and availability management. MongoDB Atlas primary-replica replication across AZs ensures data durability, while Nodemailer and Cloudinary handle transactional emails and image storage. This design delivers high availability, fault tolerance, and geographic redundancy—critical for booking platforms handling concurrent reservations.

How do I design a highly available booking platform on AWS across multiple availability zones?

This diagram shows a production-grade multi-AZ booking platform spanning us-east-1a and us-east-1b, with WAF and CloudFront protecting Node.js/Express API servers behind Application Load Balancers. MongoDB Atlas primary-replica replication ensures data consistency and failover capability, while JWT authentication and business logic handle bookings and availability across both zones.
