How to Run Code on Amazon’s EC2 Instance: A Guide

Amazon Web Services (AWS) offers a wide range of cloud-based services. One of its flagship services is the Elastic Compute Cloud (EC2), which allows users to rent virtual machines (VMs) and run their own applications. In this article, we’ll focus on how to run code on an Amazon EC2 instance.

Introduction

Amazon EC2 provides resizable compute capacity in the cloud, allowing you to scale up or down as your needs change. You can use it to host and run your code, making your application accessible from anywhere in the world. Understanding how to run code on an EC2 instance is an essential skill for any data scientist or software engineer working with AWS.

Prerequisites

Before you start, you need to have an AWS account. If you haven’t got one, you can create it by following this link.

You also need to install and configure the AWS Command Line Interface (CLI) on your local machine. Detailed instructions can be found here.

Step 1: Create an EC2 Instance

To create an EC2 instance, navigate to the EC2 dashboard in the AWS Management Console. Click on ‘Instances’ and then ‘Launch Instance’. You will be prompted to choose an Amazon Machine Image (AMI).

In this guide, we’ll use the ‘Amazon Linux 2 AMI’. Select the instance type according to your needs, then click ‘Next’. Configure the instance details, add storage, and add tags.

Next, you need to configure the security group. This is important because it determines who can access your instance. For simplicity, let’s allow traffic from anywhere for now. You can refine this later according to your requirements.

Finally, review your instance and launch it. You’ll be asked to create a new key pair or use an existing one. This key pair is used to SSH into your instance.

Step 2: Connect to Your EC2 Instance

Once your instance is running, you can connect to it. Locate your instance on the EC2 dashboard and click ‘Connect’.

You’ll find instructions on how to connect to your instance using SSH. The general command is as follows:

ssh -i /path/my-key-pair.pem ec2-user@ec2-198-51-100-1.compute-1.amazonaws.com

Replace ‘/path/my-key-pair.pem’ with the path to your key pair file, and ‘ec2-198-51-100-1.compute-1.amazonaws.com’ with your instance’s public DNS (IPv4).

Step 3: Transfer Your Code to EC2 Instance

You can use the scp (secure copy) command to transfer files from your local machine to your EC2 instance:

scp -i /path/my-key-pair.pem /path/SampleFile.txt ec2-user@ec2-198-51-100-1.compute-1.amazonaws.com:~

Replace ‘/path/SampleFile.txt’ with the path to your code file.

Step 4: Run Your Code

Now that your code is on the EC2 instance, you can run it. Let’s say you’ve uploaded a Python script. You can run it using the python command.

python SampleFile.py

Replace ‘SampleFile.py’ with the name of your Python script.

Conclusion

Running code on an Amazon EC2 instance is a straightforward process once you’ve set up your instance and transferred your code. This guide has shown you how to do just that.

Remember, EC2 instances are flexible and scalable. So, whether you’re running a small script or a large application, EC2 is a powerful tool in your AWS toolkit.

Amazon EC2 instances offer a reliable and scalable environment for running your applications in the cloud. Understanding how to run code on EC2 is a valuable skill for any data scientist or software engineer working in a cloud-based environment.
