🚀 Day 12: Create an AMI in AWS

What is an AMI in AWS?

An Amazon Machine Image (AMI) is a snapshot of an EC2 instance that includes the operating system, application server, applications, and data. It allows you to launch new instances with the same configuration quickly.

Why Create an AMI?

• Backup your instance

• Replicate environments

• Launch multiple instances from a template

• Easily restore if the instance crashes

---

Prerequisites

• An active AWS account

• At least one running EC2 instance
