Amazon ECS

Amazon Elastic Container Service (ECS) is a fully managed container orchestration service from AWS that helps users deploy, manage, and scale containerized applications. ECS simplifies the process of running containers at scale by handling the underlying infrastructure management.<br><br>Key features of Amazon ECS include:<br><br>1. Task Definitions: JSON files that describe one or more containers that form your application.<br><br>2. Clusters: Logical groupings of EC2 instances or Fargate resources where tasks run.<br><br>3. Launch Types:<br> - EC2 Launch Type: You manage EC2 instances in your cluster<br> - Fargate Launch Type: Serverless option where AWS manages the infrastructure<br><br>4. Service Scheduler: Maintains desired count of tasks and handles failures.<br><br>5. Container Registry Integration: Works seamlessly with ECR (Elastic Container Registry) or any Docker-compatible registry.<br><br>6. Load Balancer Integration: Can automatically register containers with Application Load Balancers.<br><br>7. IAM Integration: Fine-grained access control for ECS resources.<br><br>8. CloudWatch Integration: For monitoring and logging.<br><br>9. Auto Scaling: Automatically adjusts the number of containers based on demand.<br><br>When to use ECS:<br>- Microservices architectures<br>- Batch processing workloads<br>- CI/CD pipeline integration<br>- Moving containerized applications to AWS<br><br>ECS differs from EKS (Elastic Kubernetes Service) in that ECS is AWS's proprietary container orchestration platform, while EKS runs Kubernetes. ECS tends to be simpler for AWS-centric workloads, while EKS offers greater portability across environments.<br><br>For the AWS Certified Solutions Architect exam, understand how ECS integrates with other AWS services like VPC, IAM, ALB, CloudWatch, and how to choose between EC2 and Fargate launch types based on requirements for control, cost, and management.
