Blog ran on Ubuntu 16.04 for 10 years. I migrated it to FreeBSD

A blogger has migrated a website that had been running on Ubuntu 16.04 for over ten years to a FreeBSD system hosted on Hetzner, citing security concerns and a desire to explore BSD features. The move marks a significant change after long-term Linux use.

The website, hosted on a Digital Ocean VPS in New York, was originally running Ubuntu 16.04, an outdated LTS version no longer receiving updates for over five years. The blogger transitioned to a Hetzner virtual machine costing less than €6 per month, offering better hardware specifications.

The migration involved shifting from a Linux-based stack to FreeBSD, utilizing FreeBSD Jails for containerization, and adopting ZFS for filesystem management. The blogger aimed to improve security, manageability, and gain experience with BSD systems, which are praised for stability and security due to their integrated design.

Why It Matters

This migration illustrates the ongoing challenges of maintaining outdated operating systems and the potential benefits of switching to BSD-based systems for web hosting. It highlights how virtualization and filesystem choices can impact security, stability, and cost-efficiency for small-scale websites.

The move also demonstrates a practical example of BSD’s capabilities, particularly Jails and ZFS, which are less common in mainstream web hosting but offer advantages for security and data integrity.

Background

Ubuntu 16.04, released in 2016, reached end-of-life support in April 2021, leaving many servers vulnerable without official updates. The blogger’s previous setup was simple, serving static sites with nginx, and had been running for roughly four years without interruption. The decision to switch to FreeBSD was motivated by a desire to explore BSD features and improve security posture.

FreeBSD has long been regarded for its stability and security, with features like Jails predating Docker, and ZFS offering robust data management. The transition reflects a broader trend among tech enthusiasts to evaluate alternative operating systems for hosting and development.

“I wanted to get my hands on something different, and FreeBSD’s Jails and ZFS seemed like a good fit for my needs.”

— the blogger

“FreeBSD Jails provide a mature, sandboxed environment that can enhance security compared to traditional Linux containers.”

— technical expert

What Remains Unclear

It is not yet clear how the migration will impact long-term stability and performance of the website. The blogger has not yet completed comprehensive benchmarking or security assessments post-move.

What’s Next

The blogger plans to monitor site performance, conduct security audits, and explore further BSD features. Future updates may include detailed benchmarks and lessons learned from the migration process.

Key Questions

Why did the blogger choose FreeBSD over other operating systems?

The blogger was interested in FreeBSD’s stability, security features like Jails, and the mature ZFS filesystem, which offers snapshots and data integrity benefits.

What are Jails and how do they compare to Docker containers?

Jails are a form of virtualization that sandbox applications within FreeBSD, sharing the kernel but isolated from each other. Unlike Docker, Jails are more like mini-VMs with a longer history and integrated security.

Will the website’s performance improve after the migration?

Performance assessments are still ongoing, but the new server’s hardware and filesystem improvements aim to enhance stability and load times.

Are there security benefits to switching to FreeBSD?

Yes, FreeBSD’s integrated security features, such as Jails and ZFS snapshots, can reduce attack surfaces and simplify backups, potentially improving overall security.
