About This Architecture

Multi-AZ real-time collaboration platform leveraging CloudFront CDN, ALB, EC2, ECS, Lambda WebSocket handlers, RDS with failover, DynamoDB global tables, and ElastiCache Redis across two availability zones in AWS. Traffic flows through WAF and CloudFront to an Application Load Balancer distributing requests to frontend EC2 instances and backend ECS services, while Lambda WebSocket handlers manage real-time connections via ElastiCache. Data persistence spans RDS Primary/Standby for relational data, DynamoDB Collab State with cross-AZ replication for collaboration metadata, and Redis for session state, with API Gateway orchestrating integrations to Auth0, Slack, and third-party APIs. This architecture demonstrates high availability, low-latency real-time messaging, and graceful failover across regions. Fork and customize this diagram on Diagrams.so to adapt subnet ranges, instance types, or add additional AZs for your collaboration workload. The design prioritizes blast radius isolation through separate subnets for app, data, and integration tiers while maintaining cross-AZ redundancy for all stateful components.

How do I architect a highly available real-time collaboration platform on AWS with automatic failover across availability zones?

This diagram shows a production-grade multi-AZ design using CloudFront for global edge caching, ALB for request distribution, ECS for backend services, Lambda WebSocket handlers for real-time messaging via ElastiCache, and RDS Primary/Standby with DynamoDB cross-AZ replication for data durability. Separate subnets isolate app, data, and integration tiers while WAF protects against attacks.
