Containers on 🏠

32. ECS

ECS (Elastic Container Service)#

Modern applications are increasingly built as collections of small, independent services packaged in containers. Containers are lightweight, portable, and consistent across environments — but running them reliably at scale introduces real operational complexity: Where do containers run? How do you restart failed ones? How do you distribute traffic? ECS is AWS’s answer to these questions. It is a fully managed container orchestration service that handles scheduling, placement, scaling, and lifecycle management of Docker containers on your behalf — without requiring you to operate Kubernetes.

33. ECR

ECR (Elastic Container Registry)#

When you containerize applications, you need somewhere reliable to store, version, and distribute your Docker images. ECR is AWS’s fully managed container registry that solves exactly this: it gives you a private, secure, and highly available place to push images from your CI/CD pipeline and pull them into ECS, Fargate, or EKS at deploy time. Because ECR lives inside AWS, image pulls stay on the AWS network — no egress costs, lower latency, and no dependency on Docker Hub availability. 🔗

34. Fargate

Fargate#

AWS Fargate is a serverless compute engine for containers that works with both ECS and EKS. It eliminates the need to provision, configure, or manage EC2 instances for running containers — you define what your container needs (CPU, memory, networking), and AWS handles everything underneath. Fargate exists to solve a very specific operational burden: cluster capacity management. With EC2 launch type, you’re responsible for the EC2 instances that form your cluster — choosing instance types, managing scaling of the underlying fleet, patching the OS, and ensuring there’s always enough capacity. Fargate removes that entirely. You pay per task, per second, for exactly the resources your container consumes. 🔗
