☁️ Practical 2: Launch Your First Amazon EC2 Instance

AWS EC2

Objective: Deploy a virtual machine on AWS using Amazon EC2 properly configured with a secure key pair.

🖥️ Method 1: Console / GUI Guide (AWS Management Console)

If you prefer to provision infrastructure manually via the Management Console, follow these steps:

  1. Log In: Access the AWS Management Console and navigate to the EC2 Dashboard.
  2. Create Key Pair: Click Key Pairs on the left pane and create a new RSA key pair named cloud-key (download the .pem file).
  3. Initiate Launch: Click Launch instances.
  4. Choose OS: Name the instance and select the Amazon Linux OS image.
  5. Select Key: Select the cloud-key key pair you just created.
  6. Launch: Click Launch instance.
  7. Verify & Connect: Wait for it to become Running, then connect via EC2 Instance Connect or using an SSH client connecting to the Public IPv4 address using your downloaded .pem file.

🚀 Method 2: Automated Script Guide

For rapid, reproducible deployments, use the provided bash scripts.

🔍 Script Analysis

Script Name Action Performed
2computedeploy.sh 🟢 Generates a fully configured EC2 instance utilizing a designated SSH keypair (cloud-key). It automatically sets up a stylized computing dashboard webpage to verify the server is running.
2computecleanup.sh 🔴 Cleans up the instance, the associated security group, and entirely removes the private key .pem file from your local machine.

🛠️ Usage Instructions

Prerequisites:

  • AWS CLI installed and configured with active credentials.

Execute the following commands from the root directory:

# 1. Navigate to scripts folder
cd scripts/

# 2. Provide execution permission
chmod +x 2_compute_deploy.sh 2_compute_cleanup.sh

# 3. Launch specialized EC2 instance and key pair
./2_compute_deploy.sh      

# 4. Terminate EC2 instance and clean local keys
./2_compute_cleanup.sh
