# Day 38: Deploying Containerized Applications with Amazon ECS

Welcome to Day 38. Today we will learn how to deploy containerized applications with Amazon ECS.

### What is AWS ECS?

**Amazon Elastic Container Service (ECS)** is a fully managed container orchestration service provided by AWS. It allows you to run, scale, and manage Docker containers without having to install or operate your own cluster management software.

### Core Concepts

* **Task Definition:** A JSON file (the "blueprint") that describes one or more containers. It specifies parameters like the Docker image to use, how much CPU/Memory is needed, and which ports should be open.
    
* **Task:** An "instance" of a Task Definition. This is the actual running container (or group of containers) on your cluster.
    
* **Service:** Manages the "desired state" of your tasks. For example, if you tell a Service to run 3 copies of a task, it will automatically restart any that crash to ensure 3 are always running.
    
* **Cluster:** A logical grouping of your tasks and services.
