Multi-AZ Next.js SSR deployment on AWS ECS Fargate with CloudFront CDN, Route 53 DNS, and RDS Aurora replication across two availability zones. Traffic flows through AWS WAF and Shield for DDoS protection, then CloudFront distributes static assets from S3 while routing dynamic requests to load-balanced Fargate containers. ECS Fargate instances connect to Aurora primary-standby databases and ElastiCache Redis replicas for session management, with Auto Scaling, CloudWatch monitoring, X-Ray tracing, and Secrets Manager for secure credential rotation. Fork this diagram to customize subnets, add additional AZs, or integrate with your CI/CD pipeline for automated deployments.
