About This Architecture

Netflix-style microservices architecture on AWS spans two availability zones with WAF, CloudFront CDN, and ALB routing traffic to API Gateways fronting containerized Auth, Billing, and Video services on ECS Fargate, plus serverless Recommendation Lambda functions. Data layer includes Aurora primary-standby databases, DynamoDB tables, ElastiCache Redis clusters, S3 video and backup storage, Kinesis streams, and SageMaker recommendation models—all replicated across AZ-1 and AZ-2 for resilience. This multi-AZ design eliminates single points of failure, ensures automatic failover, and demonstrates Netflix's approach to handling millions of concurrent users with sub-100ms latency.

How do you design a Netflix-style microservices platform on AWS that handles millions of concurrent users across multiple availability zones?

This diagram shows a production-grade multi-AZ architecture using ECS Fargate for Auth, Billing, and Video services, Lambda for Recommendations, and Aurora primary-standby databases with DynamoDB and ElastiCache replicas across AZ-1 and AZ-2. CloudFront CDN, WAF, and ALB provide edge caching and DDoS protection, while EventBridge, Kinesis, and SageMaker enable real-time recommendations and analyti
