Event-Driven SaaS Platform on AWS
An interactive, explorable production topology featuring edge security, a multi-AZ VPC of Fargate microservices, an asynchronous event backbone, and cross-cutting security, observability & CI/CD planes. Filter any plane or run a live request trace right in the browser.
- Edge & Network Security. WAF-fronted edge protecting a multi-AZ VPC that isolates public and private service tiers.
- Event Backbone. Decoupled Fargate microservices communicating asynchronously through an event-driven messaging layer.
- Cross-Cutting Planes. Toggle security, observability, and CI/CD overlays to see how each concern threads through the platform.
Multi-Region Active-Passive Failover with Auto-Recovery
A production-grade, event-driven disaster-recovery blueprint designed to survive catastrophic regional failures while preserving client connectivity.
- Edge Resiliency. Amazon CloudFront Origin Groups route traffic away from a failing origin instantly, without waiting for slow DNS TTL cutovers.
- Automated State Recovery. CloudWatch monitors 5xx errors, alerts via SNS, and triggers a Lambda function that promotes the standby RDS PostgreSQL replica, with no manual intervention.
- Graceful Degradation. An S3-hosted static maintenance page catches user traffic during the brief promotion window, preventing transaction timeouts.
