# Day 13 : Create AMI from EC2 Instance

Welcome to Day 13. In this lab, you will learn how to create an AMI from an EC2 instance. The EC2 instance **datacenter-ec2** is already set up. You just need to create an AMI from this EC2 instance. You need to name the AMI as **datacenter-ec2-ami**.

### What is AMI and how it work?

An AWS AMI (Amazon Machine Image) is a **preconfigured template** used to launch EC2 instances. Think of it as a "golden image" that contains everything needed for a virtual server to start running.

### Types of AMI

| **Type** | **Description** |
| --- | --- |
| AWS managed AMI | Provided by AWS (Amazon Linux, Windows Server). |
| Custom AMI | Created by you from a running EC2 instance. |
| Marketplace AMI | Provided by vendors (e.g., Bitnami NGINX, RedHat, Cisco). |
| Community AMI | Shared by AWS community users. |

### **Why do we use AMIs?**

**1\. Launch servers quickly**

No need to install OS and apps each time.

**2\. Create identical environments**

Perfect for production, scaling, auto-scaling groups (ASG).

**3\. Backup and recovery**

You can create a “snapshot-based” backup of your system.

**4\. Scaling auto-scaling groups**

ASG uses AMIs to create identical instances during scaling.
