About This Architecture
Multi-tenant SaaS billing platform on AWS combining Route 53 DNS, CloudFront CDN, AWS WAF, and Application Load Balancer for secure global traffic routing. ECS Fargate microservices handle billing API and invoice rendering, with Stripe webhooks triggering Lambda functions that queue jobs via SQS for asynchronous processing. Aurora PostgreSQL with read replicas and ElastiCache Redis provide high-performance data access and session management, while S3 with Glacier archival implements cost-effective invoice storage. This architecture demonstrates production-grade multi-tenancy with built-in security, scalability, and compliance monitoring via CloudWatch.
