What is Amazon ECS?

Amazon ECS (Elastic Container Service) is a fully managed container orchestration service that makes it easy to deploy, manage, and scale containerized applications using Docker containers. ECS supports both EC2 launch type for running containers on EC2 instances you manage, and Fargate launch type for serverless container execution. It integrates with other AWS services like ELB, VPC, IAM, and CloudWatch for load balancing, networking, security, and monitoring. ECS provides task definitions to describe containers and supports service auto-scaling. It offers cluster management, service discovery, and secrets management through integration with AWS Secrets Manager and Systems Manager Parameter Store.
