Day 0 - Creating Your Own Server in the Cloud

Refer to Day 0 - Get Your Own Server to review your options:

Signing up with a VPS

Sign-up is fairly simple - just provide your email address and a password of your choosing - along with a phone number for a 2FA or another second method of authentication. You will need to also provide your credit card information.


Provider Instance Type vCPU Memory Storage Price* Trial Credits
AWS t2.micro 1 1 GB 8 GB SSD $18.27 Free Tier for 1 year
Azure B1 1 1 GB 30 GB SSD $12.26 $200 / 30 days + Free Tier for 1 year
GCP e2-micro 1 1 GB 10 GB SSD $ 7.11 $300 / 90 days
Oracle VM.Standard.E2.1.Micro 1 1 GB 45 GB SSD $19.92 $300 / 30 days + Always Free services
  • Estimate prices

On a side note, avoid IBM Cloud as much as you can. They do not offer good deals and, according to some reports from previous students, their Linux VM is tampered with enough to the point some commands do not work as expected.

Create a Virtual Machine

The process is basically the same for all these VPS, but here are some step-by-steps:

VM with Oracle Cloud

  • Choose “Compute, Instances” from the left-hand sidebar menu.
  • Click on Create Instance
  • Choose a hostname because the default ones are pretty ugly.
  • Placement: it will automatically choose the one closest to you.
  • Change Image: Select the image “Ubuntu” and opt for the latest LTS version
  • Change Shape: Click on “Specialty and previous generation”. Click VM.Standard.E2.1.Micro - the option with 1GB Mem / 1 CPU / Always Free-eligible
  • Add SSH Keys: select “Generate a key pair for me” and download the private key to connect with SSH. You can also add a new public key that you created locally
  • Create

Logging in for the first time

Select your instance and click “SSH”, it will open a new window console. To access the root, type “sudo -i passwd” in the command line then set your own password. Log in by typing “su” and “password”. Note that the password won’t show as you type or paste it.

Remote access via SSH

You should see a “Public IPv4 address” (or similar) entry for your server in the account’s control panel, this is its unique Internet IP address, and it is how you’ll connect to it via SSH (the Secure Shell protocol) - something we’ll be covering in the first lesson.

If you are using Windows 10 or 11, follow the instructions to connect using the native SSH client. In older versions of Windows, you may need to install a 3rd party SSH client, like PuTTY, and generate an ssh key pair.

If you are on Linux or MacOS, open a terminal and run the command:

ssh username@ip_address

Or, using the SSH private key, ssh -i private_key username@ip_address

Enter your password (or a passphrase, if your SSH key is protected with one)

Voila! You have just accessed your server remotely.

If in doubt, consult the complementary video that covers a lot of possible setups (local server with VirtualBox, AWS, Digital Ocean, Azure, Linode, Google Cloud, Vultr, and Oracle Cloud).

What about the root user?

Working on a different approach from smaller VPS, the big guys don’t let use root to connect. Don’t worry, root still exists in the system, but since the provider already created an admin user from the beginning, you don’t have to deal with it.

You are now a sysadmin

Confirm that you can do administrative tasks by typing:

sudo apt update

(Normally you’d expect this would prompt you to confirm your password, but because you’re using public key authentication the system hasn’t prompted you to set up a password - and AWS has configured sudo* to not request one for “ubuntu”).


sudo apt upgrade -y

Don’t worry too much about the output and messages from these commands, but it should be clear whether they succeeded or not. (Reply to any prompts by taking the default option). These commands are how you force the installation of updates on an Ubuntu Linux system, and only an administrator can do them.


When a kernel update is identified in this first check for updates, this is one of the few occasions you will need to reboot your server, so go for it:

sudo reboot now

Your server is now all setup and ready for the course!

Note that:

  • This server is now running and completely exposed to the whole Internet
  • You alone are responsible for managing it
  • You have just installed the latest updates, so it should be secure for now

To logout, type logout or exit.

When you are done

You should be safe running the VM during the month for the challenge, but you can Stop the instance at any point. It will continue to count toward the bill, though.

When you no longer need the VM, Terminate/Destroy instance.

Now you are ready to start the challenge. Day 1, here we go!
