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.
