Group 4: Container Orchestration
Managed container services for scalable microservices: EKS, ECS, Fargate, ECR.
Container Principle: Choose orchestration based on Kubernetes expertise, operational overhead tolerance, and workload complexity requirements.
Services & Roles
EKS
Managed Kubernetes service with full API compatibility & ecosystem.
- Native Kubernetes
- Helm & operators
- Auto scaling
ECS
Proprietary container orchestration optimized for AWS services.
- Task definitions
- Service discovery
- Load balancer integration
Fargate
Serverless compute engine for containers without infrastructure management.
- No EC2 management
- Per-task billing
- Instant scaling
ECR
Managed Docker container registry with vulnerability scanning.
- Image scanning
- Lifecycle policies
- IAM integration
Key Differences
| Dimension | EKS | ECS | Fargate | ECR |
|---|---|---|---|---|
| Orchestration | Kubernetes | AWS proprietary | Serverless | Registry only |
| Learning Curve | Steep | Moderate | Easy | Simple |
| Ecosystem | Kubernetes native | AWS optimized | Limited | Universal |
| Infrastructure | Managed nodes | EC2 or Fargate | Fully managed | Managed |
| Cost Model | Control plane + nodes | Nodes only | Per vCPU/GB | Storage + bandwidth |

Heuristics
- High C_kubernetesExpertise + C_ecosystemNeeds → EKS for Kubernetes workloads.
- Strong C_awsIntegration + C_simplicity → ECS for AWS-native apps.
- High C_serverless + C_noInfraManagement → Fargate for zero-ops containers.
- C_registryNeeds + C_vulnerabilityScanning → ECR for image management.
Anti-Patterns
- Using EKS without Kubernetes expertise (steep learning curve).
- Choosing ECS for multi-cloud deployments (vendor lock-in).
- Using Fargate for cost-sensitive high-volume workloads.
- Ignoring ECR vulnerability scanning in production.
Summary
Choose EKS for Kubernetes expertise, ECS for AWS simplicity, Fargate for serverless containers, and ECR for secure image management.
