About This Architecture

Multi-AZ influencer platform architecture combining Vue.js frontend, Node.js REST API, and NestJS GraphQL microservices across two AWS availability zones. Traffic flows through CloudFront edge, AWS WAF, and Application Load Balancer to backend services in private subnets, with PostgreSQL RDS primary-standby replication and ElastiCache Redis clustering for high availability. External integrations include MongoDB Atlas for influencer metrics, S3 for media storage, Cognito for JWT authentication, and CloudWatch for observability. This architecture demonstrates production-grade patterns for scalability, fault tolerance, and security across compute, database, and caching layers.

This diagram shows a multi-AZ AWS architecture spanning two availability zones with Node.js and NestJS microservices behind an ALB, PostgreSQL RDS primary-standby replication for data durability, and ElastiCache Redis clustering for session and metrics caching. WAF and Shield provide DDoS protection, Cognito handles JWT authentication, and CloudWatch monitors the entire stack.
