With 55+ years of combined Unix and FreeBSD experience and over 20 years operating in production cloud environments, we design, build, harden, automate, and operate infrastructure at scale.
From single-instance deployments to multi-region clustered systems, we engineer reliability, performance, and security from the ground up.
Frequently Asked Questions
Which Unix and Linux distributions do you support?
We support FreeBSD, OpenBSD, and all major Linux distributions including Ubuntu, Debian, RHEL, AlmaLinux, Rocky Linux, and CentOS. We also have experience with Solaris and other commercial Unix systems.
Do you provide ongoing systems management or just initial setup?
Both. We handle everything from initial architecture and deployment to ongoing management, patching, security hardening, and 24/7 monitoring. Many clients engage us for long-term operational support.
What is ZFS and why should I consider it?
ZFS is an advanced filesystem and volume manager that provides built-in data integrity verification, snapshots, compression, replication, and RAID-like redundancy. It is the gold standard for data storage on FreeBSD and increasingly popular on Linux.
Can you help with performance tuning on existing servers?
Yes. We use tools like DTrace, sysctl tuning, and profiling to identify bottlenecks in CPU, memory, disk I/O, and network performance. We then implement targeted optimizations for your specific workload.
Do you support hybrid environments with both FreeBSD and Linux?
Absolutely. Many of our clients run mixed environments. We design infrastructure that works across operating systems, ensuring consistent security policies, monitoring, and automation regardless of the OS.
