Imagine launching a new server, and within minutes it’s fully configured and ready to work — without a single manual action. Sounds unbelievable? But it’s a reality thanks to the cloud-init tool. This technology allows you to automatically configure a server right after launch by passing all the required parameters through a special configuration file. As a result, the system itself installs the necessary packages, sets up the web server, updates the OS, and even starts your app — all without administrator involvement.
