# ECS Architecture This high-performance container-based architecture supports images up to 100 MB and includes all advanced v8.0.0 features including transformation policies, non-S3 origin support, and administrative interface. **ECS architecture for high-performance image processing** ![\[serverless image handler alb ecs architecture\]](http://docs.aws.amazon.com/solutions/latest/dynamic-image-transformation-for-amazon-cloudfront/images/serverless-image-handler-alb-ecs-architecture.png) The high-level process flow for the ECS architecture is as follows: 1. An Amazon CloudFront distribution provides global caching and content delivery. 1. An [Application Load Balancer](https://aws.amazon.com/elasticloadbalancing/application-load-balancer/) (ALB) distributes incoming requests across multiple ECS tasks for high availability and scalability. 1. [Amazon Elastic Container Service](https://aws.amazon.com/ecs/) (ECS) tasks running on [AWS Fargate](https://aws.amazon.com/fargate/) process image transformation requests using containerized applications. 1. ECS tasks maintain in-memory caches of transformation policies and origin mappings for fast request resolution and reduced latency. 1. Images are retrieved from multiple origin types: Amazon S3 buckets or external HTTP-accessible domains based on configured origin mappings. 1. An administrative interface built with [AWS Amplify](https://aws.amazon.com/amplify/) provides policy and origin management capabilities through a secure web interface. 1. [Amazon DynamoDB](https://aws.amazon.com/dynamodb/) stores transformation policies, origin configurations, and mapping rules with high availability and performance. 1. [Amazon Cognito](https://aws.amazon.com/cognito/) provides authentication and authorization for the administrative interface. 1. (Optional) Amazon Rekognition integration for smart cropping and content moderation features.
