What I enjoy about Ubuntu Server
Ubuntu Server is a highly scalable, open-source Linux operating system designed specifically for computers that manage network services, host websites, and power cloud infrastructure. It operates headlessly (without a GUI), maximizing system resources for application performance, making it the most widely used enterprise Linux distribution.
Key Characteristics
-
No Graphical Interface: It runs entirely via the command-line, which keeps the system footprint extremely small and lightweight.
-
Shared Repositories: Despite being headless, it shares the exact same massive software repository as Ubuntu Desktop, allowing you to install any needed packages.
-
Support Lifecycle: Long-term support (LTS) releases provide 5 years of standard security updates for free, with the option for up to 15 years of extended security maintenance through Ubuntu Pro.
Common Use Cases
-
Cloud & Virtualization: Powers large-scale Kubernetes clusters, OpenStack private clouds, and containers (e.g., Docker).
-
Web & Database Hosting: Hosts Nginx or Apache web servers, MySQL/PostgreSQL databases, and application backends.
-
Network & Storage: Functions as a central NAS (Network Attached Storage) for file sharing, Plex media servers, and DNS/DHCP controllers.
Ecosystem & Tools
To streamline deployments, Ubuntu Server includes native integration with several enterprise-grade management tools:
-
MAAS (Metal as a Service): Provisions bare-metal servers as easily as launching instances in the cloud.
-
LXD: A next-generation system container manager that runs machine containers with the speed of containers and the security of virtual machines.
-
Juju: An open-source application modeling tool for deploying, configuring, and managing complex workloads across public and private clouds.
What I use Ubuntu Server for
Ubuntu has been my goto for reliable, versatile servers for many years. It's always been a staple of dependability. Everything listed under Common Use Cases is what I use Ubuntu Server for. But these days, I run them as VM's on Proxmox Hosts automatically sandboxing them from internet attacks while providing me with ready available, full system backups should anything go wrong.
For a time, I would set up Ubuntu Server as a workstation with Gnome. From there, I would setup VirtualBox with a Proxmox Node I connect with the Server to get live snapshots backed up to my development machine that would also act as full backups.
