Launching an EC2 Instance and Deploying a Web Server

Introduction

In this lecture, we explored how to launch an EC2 instance using the AWS Management Console and configure it with Amazon Linux 2. We also deployed a basic web server using the user data script and covered essential EC2 operations like starting, stopping, and terminating an instance.

1. Launching an EC2 Instance

Step 1: Accessing the EC2 Console

• Navigate to the AWS EC2 Console.
• Click on Instances → Launch Instances.

Step 2: Naming the Instance

• Assign a name using tags.
• Example: "My First Instance".

Step 3: Choosing an Amazon Machine Image (AMI)

• Select an operating system for the instance.
• Use Amazon Linux 2 AMI (Free Tier Eligible).

Step 4: Selecting an Instance Type

• Choose an instance type based on CPU, memory, and cost.
• Select t2.micro (Free Tier Eligible).

2. Configuring Key Pair for SSH Access

• Create a new key pair (e.g., "EC2_Tutorial").
