How to Use SSH with AWS EC2 on Windows: A Guide

As a data scientist or software engineer, you’ve probably utilized AWS EC2 instances for various projects. You know how crucial it is to connect to these instances securely, and that’s where SSH (Secure Shell) comes into play. But, if you are a Windows user, you might be wondering how to establish an SSH connection to your AWS EC2 instance, particularly if it’s running Amazon Linux AMI. Let’s dive into the specifics and understand how you can manage this.

What is SSH?

SSH, or Secure Shell, is a cryptographic network protocol used for secure communication between a client and a server over an unsecured network. In the context of AWS EC2, SSH allows you secure remote login from one computer to another, making it essential for managing your instances.

Setting Up Your AWS EC2 Instance

Before we delve into the process of SSH, let’s quickly review how to set up an AWS EC2 instance.

  1. Log into your AWS Management Console.
  2. Navigate to the EC2 dashboard and click on ‘Launch Instance’.
  3. Choose the ‘Amazon Linux AMI’ and follow the setup wizard. Note that during the setup, AWS will prompt you to create a new key pair or use an existing one. If you’re creating a new pair, make sure you download and securely store the .pem file. This file is crucial for SSH.

SSH into AWS EC2 from Windows

While Linux and MacOS come with a built-in SSH client, Windows doesn’t. However, you can use PuTTY, a free SSH client for Windows.

Step 1: Download and Install PuTTY

Download PuTTY from the official website and install it.

Step 2: Convert Your .pem File to .ppk Format

PuTTY doesn’t use .pem files. Instead, it uses its format, .ppk. To convert your .pem file:

  1. Open PuTTYgen (installed with PuTTY).
  2. Click ‘Load’ and select your .pem file.
  3. Click ‘Save private key’ and name your file (it will save in .ppk format).

Step 3: Connect to Your EC2 Instance

  1. Open PuTTY.
  2. In the ‘Host Name (or IP address)’ field, enter ec2-user@<your-EC2-instance-public-IP>.
  3. In the ‘Category’ pane, navigate to Connection > SSH > Auth.
  4. Click ‘Browse’ and select your .ppk file.
  5. Go back to the ‘Session’ category, save your session details for future use, and click ‘Open’.

If all goes well, a new window will open with a terminal connected to your EC2 instance.

Conclusion

Accessing your AWS EC2 instances securely is a critical part of your workflow as a data scientist or software engineer. Thankfully, with tools like PuTTY, it’s relatively straightforward to SSH into your AWS EC2 instance from a Windows machine. Remember to keep your private keys secure and never share them.
