- Using the VM is like using any other Linux machine
                          - Some exceptions exist, e.g. the start-up process (cloud-init)
                        - Available images include:
                          - AlmaLinux
                          - CentOS
                          - Ubuntu
                        - You can install and run native Linux applications (root access) or run container-based applications such as Docker.

- Set up a web server on your VM (<https://cssedu.csc.fi/cpouta/install-apache/>) and define a security group so it is reachable from the internet
                        - Create a VM using the CLI (<https://cssedu.csc.fi/cpouta/create-vm-cli/>)
                        - scp the private key to a VM with a public IP and ssh onward to a VM inside Pouta
                        - Create a security-group rule that allows connections only from a remote security group instead of an IP range
