Abstract

The growth of cloud computing and virtualization has changed how IT infrastructure is managed, moving from doing things by hand to using Infrastructure as Code (IaC) methods. This study uses Ansible as a tool for managing server setup to automate tasks on Debian 12 servers within a virtualized environment. The setup includes four main areas of administration:managing users and masing SSH more secure, setting up a firewall using UFW,insatlling the Ngnix web server with Jinja2 templates, and setting up automatic security uodates through unattended upgrades. The method used is Design Science Research (DSR), which involves an experimental approach that uses two connected virtual machines. The results show that Ansible was able to fully aautomate the setup process, taking a total of 54.121. seconds to complete. It also demonstrated that all the roles worked correctly even when run more than once, with no changes needed on re-run. This setup helps cut down on mistakes people might make, makes sure settings are the same every time, and allows for creating the same infrastructure again and again.
