About This Architecture
Multi-AZ mobile productivity app architecture on AWS with CloudFront CDN, WAF, and Application Load Balancers distributing traffic across two availability zones. ECS microservices (Auth, Room, Leaderboard, Payment, Profile, Community) and Lambda functions (Alarm, Focus Session) run in private subnets across AZ-1 and AZ-2, backed by PostgreSQL primary-standby replication, ElastiCache Redis sessions, DynamoDB global tables, and S3 asset replication. This design ensures high availability, automatic failover, and sub-millisecond session caching while integrating third-party APIs like Agora/Twilio for video and Razorpay for payments. Fork and customize this diagram on Diagrams.so to adapt subnet sizing, add additional services, or modify failover strategies for your productivity platform. The architecture demonstrates AWS best practices for resilient mobile backends handling concurrent users across regions.
