FreeBSD Jails and Linux LXC both provide operating system-level virtualization, but their design philosophies differ significantly. This article explores how each approach handles isolation, security, observability, ZFS integration, and operational complexity to help infrastructure teams determine which model best fits their environment.
Discover how OpenZFS and SeaweedFS combine to provide high-performance, scalable object storage. This guide covers architecture, deployment, and optimization on Linux and FreeBSD.
ZFS for media production allows studios to optimize storage for each department, improving performance across animation, compositing, editorial, and databases while maintaining strong data protection and simple project isolation.
With Fast Dedup in OpenZFS, duplicated data across VMs, backups, and containers can be collapsed—turning existing storage into significantly more usable capacity.
Technical independence is a critical design principle for modern storage infrastructure. This article explores how FreeBSD and OpenZFS provide transparency, hardware portability, and data portability
We successfully hired from HN in the last round and are looking for more OpenZFS Developers (4+ years of experience) to join our team!
Klara Inc. provides development & solutions focused on open source software and the community-driven development of OpenZFS and FreeBSD. We develop new features, investigate/fix bugs, and support the community of these important open source infrastructure projects. Some of our recent work includes major ZFS features such as Linux Containers support (OpenZFS 2.2: https://github.com/openzfs/zfs/pull/12263), and Fast Deduplication (OpenZFS 2.3: https://github.com/openzfs/zfs/discussions/15896).
We’re looking for an OpenZFS Developer with:
- Strong C programming skills and solid understanding of data structures
- Experience with file systems, VFS, and OS internals (threading, locking, IPC, memory management)
- Familiarity with ZFS internals (DMU, MOS, vdevs, ZPL, datasets, boot environments)
- Ability to work across Linux, FreeBSD, or illumos environments
Upstream contributions to OpenZFS or other open source projects are a big plus.
