About This Architecture

ServiceLink FixFinder implements a resilient three-tier architecture spanning two AWS availability zones with WAF, CloudFront CDN, Route 53 DNS, and Application Load Balancer routing traffic to React.js frontends and Spring Boot REST APIs. The Business Logic Layer enforces JWT authentication and Spring Security across Booking Management and Service Management modules, while the Data Layer uses RDS MySQL Primary-Standby replication for high availability. This architecture demonstrates AWS best practices for fault tolerance, security, and scalability in multi-tenant service marketplaces. Fork this diagram on Diagrams.so to customize subnets, add caching layers, or integrate additional AWS services like ElastiCache or SQS. The dual-AZ design with synchronized databases ensures zero-downtime deployments and automatic failover.

How do I design a highly available three-tier AWS architecture with database replication and multi-AZ failover?

ServiceLink FixFinder demonstrates a production-grade three-tier AWS design: WAF and CloudFront protect the edge, Route 53 and ALB distribute traffic across two AZs, Spring Boot backends handle REST API requests with JWT/Spring Security, and RDS MySQL Primary-Standby replication ensures data consistency and automatic failover. This pattern supports zero-downtime deployments and handles regional ou
