What is Debian?
Debian is one of the oldest and most respected Linux distributions. Since 1993, Debian has been known for its stability, security and the enormous package repository with 59,000+ software packages. Debian forms the basis of Ubuntu and many other distributions.
Why Debian is useful
For servers and production environments, stability is crucial — Debian delivers that:
- Exceptional stability: Extensively tested releases that run for years
- Security updates: Dedicated security team with fast patches
- 59,000+ packages: The largest software repository of all Linux distributions
- Multi-architecture: Runs on x86, ARM, RISC-V and more
Time savings with Debian
Debian servers require minimal maintenance thanks to the reliable package manager and long support cycles (5+ years per release).
APT Package Manager
Install, update and remove software reliably with automatic dependency handling.
Stable Release
Extensively tested releases that are perfect for production servers without surprises.
Security Team
Dedicated team that quickly patches security vulnerabilities — including for older releases.
Unattended Upgrades
Automatic security updates without intervention so servers are always protected.
Hidden features that often go unused
Debian offers much more than a basic installation:
- Backports: Newer software available on the stable release without upgrading.
- Preseed: Fully automated installation for identical servers.
- AppArmor: Mandatory access control to sandbox applications.
- systemd Timers: More flexible alternative to cron with better logging.
- LXC & Docker: Container support natively built in.
- Multiple Architectures: Multiarch support for running 32-bit software on 64-bit.
Integrations with other tools
Debian integrates with many other tools and services:
Kubernetes
Node.js
PostgreSQL
- Docker: Most Docker images are based on Debian.
- Kubernetes: Debian as the base OS for container nodes.
- All programming languages: Python, Node.js, PHP, Java — everything available via APT.
