I want to learn how to run my own server but I don't know where to start. The concept of self-hosting is appealing as a way to keep my data under control. Is it possible to run applications on my own devices instead of using a private cloud service? What are the basic steps to follow? If anyone has experience with this, what should I be careful about? I'd love to hear your thoughts!
What is Self-Hosting and How Do You Get Started?

Starting with self-hosting, first you need to clarify the basic hardware requirements. A raspiyat (e.g., Raspberry Pi 4/5) or an old laptop/diskless PC is ideal: low power consumption, silent operation, and sufficient storage (at least 500GB SSD) are recommended. My preference was setting up Ubuntu Server 22.04 LTS on a Raspberry Pi 4—it’s stable and supports ARM-based applications. As a first step, flash the *dietpi* or *ubuntu-server* image to a microSD card and make it manageable via SSH. For the power supply, use a stable adapter (e.g., 5V/3A), especially when connecting drives.
Next, consider your network infrastructure. Assigning a static IP (via the router) or setting up dynamic DNS with tools like ddclient is essential for external access. I use *Cloudflare Tunnels* (formerly Argo)—this way, you don’t need port forwarding, and SSL certificates are automatically configured. Tools like Portainer or Cockpit simplify container and system management in the long run.
Data protection is critical, so a backup strategy is vital. I prefer *BorgBackup* + an external HDD—frequent backups and encrypted data provide both security and flexibility. When selecting applications, I prioritize stability: for example, opting for *Immich* (photo management) over *Nextcloud* or *Vaultwarden* (a Bitwarden fork) over the original. Finally, protecting against security vulnerabilities with *fail2ban* and keeping the system updated automatically are the most overlooked yet critical parts of self-hosting.
