Cloud Architecture Guide
Amazon ECS vs EKS
Deciding between AWS-native Docker simplicity or the industry-standard Kubernetes powerhouse.
The Ingredients
What drives the decision for your infrastructure stack?
ECS Ingredients
The “AWS-Native” Approach
- Proprietary Control Plane: Built by AWS for AWS.
- Deep Integration: Seamless IAM, CloudWatch, and ALB support.
- Simplicity: No Kubernetes manifest complexity; use task definitions.
EKS Ingredients
The “Open-Standard” Approach
- K8s Control Plane: Managed Kubernetes (upstream compatible).
- Ecosystem Power: Access to Helm, Istio, and Prometheus.
- Portability: Standardized API for hybrid or multi-cloud.
The Orchestration Workflow
Developer
ECS (Task Definitions)
EKS (YAML Manifests)
Shared AWS Compute (EC2/Fargate)
1. Define
Code your app and package it as a Docker image stored in ECR.
2. Orchestrate
Choose ECS for ease-of-use or EKS for granular control over scheduling.
3. Deploy
Launch on Fargate (Serverless) or EC2 (Managed Instances).
