Previously, to experience Linux OS, you needed to install Linux OS on your computer; however, it became easier to set up the Linux environment on public cloud infrastructure or VPS (Virtual Private Server). Throughout this course, we'll be using Linux Ubuntu OS on AWS Lightsail service to demonstrate Linux operations. AWS Lightsail is a VPS. AWS Lightsail is a light version of AWS EC2. Without detailed configuration, you can set up the Linux OS environment very quickly. As AWS Lightsail offers the first three months free, you can use Linux OS at no additional cost.

On Lightsail Home, press the Create Instance button.
Select Linux/Unix as a platform and select Ubuntu (20.04 LTS) under the OS only selection.

After pressing the Create instance button, you'll see that Ubuntu OS is being prepared. While the icon is gray, instance creation is still pending.
Once the instance is launched, you can see that icons change color. Click the Ubuntu OS panel to see the details of the OS.

You can also directly open the command line from the Instance panel. Click on the orange command line icon to launch the command line.
The command line will show up in a new window as shown in the image below. Now you are ready to use Linux OS.
