Multi-AZ Streamlit ML inference app deployed on AWS ECS Fargate with high availability across us-east-1a and us-east-1b. Developers push container images to Amazon ECR, which triggers ECS Fargate services in public subnets with assigned public IPs and inbound TCP 8501 security group rules. Users access the Streamlit app through the Internet Gateway, while both Fargate tasks stream application logs to CloudWatch under /ecs/mlops-heart-disease for monitoring and debugging. This architecture demonstrates containerized ML model serving with built-in observability, eliminating server management overhead while maintaining fault tolerance across availability zones.
