I recently considered switching my server deployments from Linux to FreeBSD. I need to move a number of sites off a dedicated server to either a different dedicated server (less money), or to a vps (much less money). Since I have to go through some pain with switching, I figured now was a good time to try and decide whether I should stick with Linux (Debian/Ubuntu) or move to FreeBSD.
After spending too many hours researching and experimenting (multiple installations of FreeBSD & lots of software built/installed), I’ve decided to stick with Linux for hosting web applications. Here are some advantages for each OS from my perspective.
- A slight performance advantage currently from my research, but this is debatable
- My primary desktop is Mac OSX which is based on FreeBSD, so I would be able to leverage sysadmin knowledge between my development machine and my hosted machines. This is the same advantage I had when my main development machine was Ubuntu and I hosted apps on Ubuntu. However, OSX doesn’t require much Unix sysadmin knowledge, so this isn’t nearly as important as the analog below.
- I like the idea of building packages from source, and the ports system does this very nicely.
- The organization of the OS seems superior to me. The ports system, startup scripts, file locations, etc.
- Paul Graham’s server OS of choice (at least for news.ycombinator.com), so I expect Arc will continue to be well supported on it (that is if Arc continues itself)
- Yahoo & other large sites use it.
- Ubuntu is a much better desktop OS, and I’ve decided to use it on my non-Mac home computers, so I can leverage sysadmin knowledge between my home machines and hosted machines. The desktop installation for Ubuntu 8.04 is unbelievably nice. If I ever become dissatisfied with OSX as my primary desktop, I’ll switch back to Ubuntu in a heartbeat. I just loaded Ubuntu 8.04 on my old 900 MHz AMD w/ 384 MB RAM, and it’s quite responsive.
- I’ve accumulated more sysadmin knowledge for Linux than for FreeBSD, and supporting two operating systems (OSX / Linux) is more appealing than supporting three.
- Better virtualization support
- Linux threading seems to perform better (although FreeBSD has caught up a little)
- Companies such as slicehost.com support Linux, but not FreeBSD (due to virtualization issues), so this limits my options with FreeBSD
- Auto power management works out of the box – shutdown the OS and the computer powers down
- The binary package system is much faster for installations. If I need to get another web server up and running quickly, I can do it much easier with Debian/Ubuntu than with FreeBSD.
- Google & other large sites use it
The two operating systems seem quite close to me, and it’s possible I’ll make a different decision a year or two down the road, but for now, the cost of switching from Linux to FreeBSD is higher than any expected benefit – particularly since my code rests upon Apache, Mongrel, Ruby, Rails, etc.
I have an emotional bias toward BSD since I started out on SunOS (as far as Unix is concerned), and it seems to have a richer history; however, Debian/Ubuntu seems to be the most practical choice for me at this time.
Even though I ended up sticking with my current server platform, I do feel better about having performed my due diligence rather than continuing with a default, and I have some really great notes for setting up a FreeBSD system should I need to do so in the future
- 365.25 days per year
- 12 months per year
- 24 hours per day
- 60 minutes per hour
- 60 seconds per minute
- 1,024 MB per GB
- 1,024 KB per MB
- 8 kilobits (kb) per kilobyte (KB)
Put that all together and you get the following:
3.19 (month kb) / (sec GB)
So when you see a web hosting company stating a bandwidth per month (in GB), you can multiply that by 3.19 to get a kilobits per second figure. In other words, 18 GB/month of bandwidth is the amount of bandwidth that a 56Kb modem would consume at full capacity, and 480 GB/month is roughly the same as a 1.5Mb T1 line.
