ECS Optimized Ubuntu 20.04 – Getting Started

This guide will help you quickly get started with our AWS Marketplace offering – ECS Optimized Ubuntu 20.04 Image.


ECS is a fully managed container orchestration service from AWS that makes it easy for you to deploy, manage, and scale containerized applications. Containers are defined using task definitions and run as services across a fleet of Amazon EC2 instances. ECS can automatically scale up your applications to meet a spike in demand or scale down when demand is less, leading to cost-effective operations in the cloud.

Underneath this robust AWS container orchestration solution is Docker, an industry-standard container runtime engine and the ECS agent responsible for scheduling services across your clusters.

This listing bundles this robust orchestration solution with Ubuntu Linux, a rock-solid Linux Operating System, into a single 1-Click deploy Optimized AMI.
