🚀 Getting Started with AWS Fargate & ECS

If you're stepping into the world of AWS Fargate and ECS (Elastic Container Service), here's a quick and easy guide to understand the basic components. This will help you get started with running containers in a serverless way!

📦 1. Container Definition

A container definition includes:

• The container image (e.g. from Docker Hub or ECR)
• Container-level settings such as: - Ports, Registry details, and Environment variables
• 🔸 These settings apply to individual containers.

🧱 2. Task Definition

A task definition is like a blueprint for your application.

• It describes one or more containers using configuration attributes.
• Most settings are defined per container, not at the task level.
• If multiple containers are used together, they’re combined into one task.

⚙️ 3. Service

A service helps you:

• Run and maintain a specific number of task instances (called desired count).
• Automatically restart tasks if they stop.
• Ensure high availability in your ECS cluster.

🛠️ 4. Fargate Cluster

• A Fargate cluster is fully managed by AWS.
• No need to manage EC2 instances or underlying infrastructure.
• You just define your container requirements, and AWS handles the rest.

🚀 5. Task

A task is the running instance of a task definition.

• A task is the running version of a task definition.
• You can run tasks directly or through a service.
• Each task in Fargate runs in its own isolated environment: - It doesn’t share CPU, memory, or network with other tasks.

🧠 Final Thoughts

Using Fargate with ECS lets you focus on your app while AWS takes care of the heavy lifting. No server management, no EC2 setup — just define your containers and go!
