About This Architecture

Multi-AZ YouTube-style streaming platform leveraging Route 53, CloudFront CDN, and WAF for global content delivery and DDoS protection. Traffic flows through API Gateway and Cognito to containerized microservices (ECS React Frontend, Flask API, Video/User/Comment/Notification Services) across two availability zones with Auto Scaling, while Lambda Transcoders process video uploads via SQS queues. Data layer spans RDS PostgreSQL with read replicas, ElastiCache Redis for sessions, DynamoDB for distributed state, and S3 for video storage with cross-AZ replication. This architecture demonstrates enterprise-grade resilience, auto-scaling, and separation of concerns critical for handling millions of concurrent users. Fork and customize this diagram on Diagrams.so to adapt tier sizing, add additional regions, or integrate third-party analytics. The design balances cost optimization through spot instances and reserved capacity with fault tolerance via multi-AZ redundancy and automated failover.

People also ask

How do I architect a scalable YouTube-like streaming platform on AWS with multi-AZ failover and video transcoding?

This diagram shows a complete streaming architecture using Route 53 for DNS failover, CloudFront for global CDN delivery, and ECS microservices across two AZs for redundancy. Video uploads trigger Lambda transcoders via SQS, while RDS PostgreSQL with standby replicas, ElastiCache Redis, and DynamoDB ensure data consistency and session management across zones.
