About This Architecture

AWS mobile application backend architecture combines Amplify, AppSync GraphQL API, and Cognito authentication with multi-tier compute and data layers. CloudFront and WAF protect the edge, routing authenticated requests through AppSync to an Application Load Balancer distributing traffic across ECS Fargate containers, EC2 t3.medium instances, and Lambda functions. The private app tier connects to RDS db.t3.small PostgreSQL, ElastiCache for session caching, and EFS for shared storage, with all secrets managed by Secrets Manager and data encrypted via KMS. This architecture demonstrates AWS best practices for mobile backends: managed authentication, GraphQL federation, container orchestration, automated backups via AWS Backup, and cost visibility through Cost Explorer.

How do I architect a scalable mobile backend on AWS with authentication, GraphQL API, and multi-tier compute?

Use AWS Amplify for frontend hosting, Cognito for authentication, AppSync for GraphQL API federation, and distribute backend load across ECS containers, EC2 instances, and Lambda functions connecting to RDS and ElastiCache in private subnets. This diagram shows the complete flow from CloudFront edge to encrypted data tier with Secrets Manager and KMS.
