Active Info relies upon and develops with the advanced FreeBSD open operating system
that derives directly from the original Berkley Unix. We've been runing production
servers with FreeBSD for over six years without problems. Our experience has shown us how very reliable
FreeBSD has been for production situations. It just keeps running.
Compelling Technical Advantages of FreeBSD:
There is a very long list of
reasons why FreeBSD is an excellent operating system and an ideal choice
for the enterprise and the desktop. Briefly:
Netgraph provides unparalleled flexibility to build complex network
Netgraph modules are available for packet filtering,
tunneling, redirection, inspection, and injection at any point in the
network stack in a transparent and quick fashion. Modules can be
stacked together like bricks to meet just about any need. Developing
custom modules is also easy and very well documented. There simply is
not anything else in any other OS that is as flexible, easy to use, and
full-featured as netgraph.
GEOM provides to the storage stack what netgraph provides to the
Transformations like mirroring, striping, spanning, and
encryption can be configured for any storage object from the filesystem
on up. The vinum volume manager was recently converted to use GEOM and
now provides high-availability and high-reliability redundancy to any
storage object. While NetBSD recently imported Vinum, it took the
older, less stable and less functional version that has since been
deprecated by its author in FreeBSD in favor of GEOM-Vinum.
Advanced network features and protocols
such as SACK, NFSv4,
SYN-cache/SYN-cookies, compressed TIME_WAIT, and accept filters allow
for fast, secure, and scalable network operations in an ever-increasing
hostile and busy Internet. Packet filters like IPFW and PF provide
advanced filtering, shaping, and NAT sharing. FreeBSD continues to run
some of the busiest and most important network sites in the world with
Outstanding desktop and laptop support is provided by a number of
Nvidia develops and distributes native 3D drivers for its
graphics cards for FreeBSD. A team of FreeBSD developers works closely
with engineers at Intel to provide the best ACPI power management
support available in an open source operating system. The Gnome and KDE
desktop environments work flawlessly under FreeBSD thanks to another
team of volunteers that work closely with those projects.
The "Ports" collection provides one-step support for over 11,000 3rd
Compile-time and run-time dependencies between
applications and libraries are tracked and handled automatically,
eliminating conflicts and incompatibilities. Pre-compiled binaries are
available for nearly every supported package for quick and easy
installation. This system continues to be one of the crown jewels of
FreeBSD and has been copied by other OSes due to its overwhelming
Many commercial vendors also support FreeBSD.
Companies like Intel,
AMD, LSI, Adaptec, and 3Ware, just to name a few, provide development
staffing, direct developer resources, and end-user support for many of
their products. The result is high quality drivers, applications, and
platform support for a wide range of modern hardware.
Continuous testing and QA is performed by a number of teams within the
Tests are runs every day that range from simple
full-tree compile runs to intensive network, I/O, and computational
stress tests. Developers receive status emails and bug reports to help
identify, track, and resolve defects. While no amount of testing is
perfect and bugs do slip through, the testing that exists vastly exceeds
the efforts of most other open source projects and contributes towards
every FreeBSD release being high quality.
FreeBSD is still the 'silent workhorse' that runs
corporate networks and powers advanced appliances. However, it's time
to drop the 'silent' part and start loudly advocating it. FreeBSD is an
outstanding OS, and developers and users should be proud of it.
