Let's start by creating an instance in an AWS Free Tier account. First, navigate to the AWS dashboard and select EC2.
After that, a new webpage will open. Now select "Launch Instance" to configure and set up the instance.
You can select the number of instances depending on your requirement, but I suggest one instance is enough for today's hands-on practical. Do name your instance to identify it for later use. Choose the Ubuntu Linux AMI and make sure the AMI server you choose is Free Tier eligible so that you won't be charged. For your reference, I have highlighted the Free Tier eligible AMI server.
As we move forward with the practical, do create a key pair. This is not essential but is one of the best practices as it provides a secure and convenient way of authenticating and accessing your resources.
I'll skip some setup configurations and want you all to skip them this time as this is an initial-level practical. Let all other configurations remain at their default settings and click on "Launch Instance." After you have launched the instance, check for the instance state. When it turns green and running ✔️, click on "Connect."
Navigate to EC2 Instance Connect and connect to the Ubuntu server through the browser-based client where you can practice your Linux commands on a real-time Ubuntu server for better understanding.
