What is Amazon ECS?
Amazon Elastic Container Service (ECS) is a fully managed container orchestration service from AWS. It enables running, stopping, and managing Docker containers on a cluster without managing the orchestration infrastructure yourself. ECS integrates seamlessly with other AWS services like IAM, CloudWatch, VPC, and Application Load Balancer.
Core Features
- Task Definitions: Declarative configuration for containers with CPU, memory, networking, and volumes
- Service Scheduler: Automatic maintenance of desired task count with health checks
- Capacity Providers: Flexible resource management with EC2, Fargate, or Spot instances
- Service Discovery: Automatic DNS-based service discovery via Cloud Map
- Secrets Management: Integration with Secrets Manager and Parameter Store for sensitive data
Typical Use Cases
Microservices Architectures: ECS is ideal for microservices. Each service runs in its own containers with independent scaling and deployment. The Application Load Balancer distributes traffic based on path-routing or host-based rules.
Batch Processing: For batch jobs, ECS allows starting containers on demand and automatically stopping them after completion. Combined with Spot instances, costs can be reduced by up to 90%.
Web Applications: ECS enables deployment of web applications with automatic scaling based on CPU, memory, or custom CloudWatch metrics.
Benefits
- No control plane costs: You only pay for the AWS resources used
- Deep AWS integration: Native connection to IAM, CloudWatch, VPC, and other services
- Simpler learning curve: Less complex than Kubernetes for AWS-native deployments
- Flexible compute options: EC2, Fargate, or Spot instances depending on requirements

Frequently Asked Questions
What is the difference between ECS and EKS?
ECS is an AWS-native container orchestrator with a simpler learning curve and deeper AWS integration. EKS uses Kubernetes and is better suited for multi-cloud strategies or when Kubernetes expertise already exists.
Can I run ECS with Fargate or EC2?
Yes, ECS offers both launch types. Fargate is serverless and requires no server management. EC2 provides more control and can be more cost-effective for constant workloads.
How does deployment work in ECS?
ECS supports rolling updates, blue-green deployments via CodeDeploy, and external deployment controllers. You define Task Definitions and Services that automatically maintain the desired state.
Can ECS be used in a GDPR-compliant way?
Yes, ECS is available in EU regions (Frankfurt, Ireland, Paris) and can be operated GDPR-compliant. AWS provides appropriate data processing agreements.
