Linux TCO: Less Than Half The Cost of Windows
ggruschow writes "Linux Today reports 'The cost of running Linux is roughly 40% that of Microsoft Windows, and only 14% that of Sun Microsystem's Solaris, according to a new study which examined the actual costs of running various operating systems over three years.'"
They throw in a few eye catching facts, such as this:
The Windows technicians, however, only managed an average of 10 machines each, while Linux or Solaris admins can generally handle several times that.
Good enough for you?
The PDF for the study is hosted on IBM's website... I'd be willing to bet that it was IBM that commissioned the study. Anybody know?
;-)
**begin sarcasm**
What a big suprise that would be if a study funded by IBM finds that their Linux solutions perform better than Windows and Sun!
**end sarcasm**
That said, it is nice to have some pro-Linux FUD out there!

I am assuming that the Linux and Solaris admins are using the CLI to manage the servers via SSH but I believe the slowest way to manage a server is through a keyboard and mouse -- pointing and clicking away. Most of the Windows servers I have managed in my career were through a GUI interface using a remote control program like PC Anywhere and Microsoft's Remote Admin software. With Linux, Solaris and now Mac OS X Server, I use SSH and a keyboard to do my work. With shell scripts and other tricks, I can blaze through server management that I would never be able to do in a GUI environment at the same speed. Even with Mac OS X Server's great GUI management tools, I prefer to fire up Terminal and remotely manage the system through a CLI -- or maybe I just long for the days of my Apple ][.
On the other hand, with the massive numbers of zombied Windows machines probing my networks, it could be that Windows-only Admins are just plain idiots with a MCSE which accounts for the productivity gains of Linux and Solaris admins.

Last year we decided to migrate off Windows.
We first moved to OpenOffice. Painful, when your clients all use MS Office, but it's possible.
Now we're moving to Mozilla-based browsers.
All our servers (except one) went to Linux in the last year or two.
Now we're killing the last Windows desktops, putting Lindows-OS in their place.
Apart from the license savings, everything just runs better.
There is a huge fear of change, and this works in Windows' favor.
But there is no doubt that open software is better built and cheaper to run.
Changing costs something. But there is no doubt about the TCO of Linux (and its applications) being lower.
Sig for sale or rent. One previous user. Inquire within.
If they want to do TCO of apples to apples, maybe they should have used Sun LX-50 x86 box, instead of their Enterprise class machines. There are feature sets in that class of machine (eg domaining, redundant hardware, hotswap etc) that are just not available in an x86 box. The cost of those features greatly inflates the TCO for Solaris.

At the last place I worked there was one *NIX admin (me) who was responsible for 15 HP-UX machines, a couple of Sun boxen, one lone AIX machine, and about 10 Linux boxen, I was also the webmaster and one of the NT/2K admins. There were 4 dedicated NT/2K admins for about 25 machines and they were always busy working on the machines. If it wasn't exchange dying or the DNS crapping out on us it was some wierd WINS issue or a virus. These guys were very talented admins too, not the MCSE tripe that comes out of the pipe now. Linux TCO is much much lower, I've been preaching this for a long time. I'm not saying that *NIX is perfect or never has a problem, but it is much rarer and the problems are usually easier to fix than the self corruption that goes along with Windows.

At UCSD, the Microsoft Assimila... err Microsoft Student Rep essentially crashed our "Linux Setup Day" event a couple years ago and handed out free copies of Windows 2000.
.net, etc. right now on campus.
The MS student rep would give out free copies of Windows, Visual Studio, Office, etc. on campus, and I'm sure that Microsoft is giving out free copies of WinXP, Visual Studio
The thing is that Microsoft did NOT do this sort of thing on such a wide scale until Linux grew in popularity on campus.
MS is obviously trying very hard to keep CS students from learning to seriously develop software outside of a Microsoft Environment.
By providing students with MS software for free, they hope to stop students from using open source development tools.
If Windows is all programmers know, that is all they'll develop for.

I was principal architect for Excite Clubs for 4 years. During a period of one year, we went from 100K page views to over 20M page views a day.
,the page generation times went down to .1 seconds and the highest observable CPU load was less than 10%.
We had a rather unique situation. We started the project on Windows NT 4.0 and later migrated to Win2K. During that time, we were barely able to handle 1M page views per day on the windows boxes. In addition, the average page generation time was 2 seconds. The 20 windows boxes we had in production cost approximately 17K a piece (quad compaq proliant with 1 gig of ram) and were all experiencing 80% or more CPU usage.
The 20 boxes were managed by 1 sysadmin (6 years experience from MS consulting services) with a full time assistant. This does not count the high school students we had wandering the racks hard rebooting terminally ill boxes.
Most admin time was spent on upgrades, boxes that would just stop working (we called it spontaneous server rot) and trying to use a host of opaque, inadequate tools to detect and eliminate bottlenecks. Build, rollout and staging tools were also a big time synch. Finally, the installation of software onto a new machine in the right order with all configuration parameters took an extradinary amount of time.
In addition, I had one full time engineer writing noting but 'nanny' programs to monitor the program and restart the process when there were problems.
With all this work, the system still went down daily.
After much politicking we translated the program to JSP (straight page per page translation) and moved to solaris machines. The java middle tier ran as on solaris. The 20 compaq boxes were replaced with 16 solaris boxes. Oddly, we paid almost the same amount per box (20K versus 16K).
Immediately, we were able to more that 5M pageviews per day with no changes to the software. In addition
Our sysadmins were replaced with a part time (less than 5 hours per week) solaris admin. The roll out scritps were trivial to write and maintain. We had very few upgrades/security patches.
Most important, the host of tools provided to monitor system performance and tell exactly where bottle necks were and the truly deep understanding of the system internals by the sys admins allowed us to eliminate the remaining problems and scale to 20M pageviews per day.
That is right. two orders of magnitude better performance for precisely the same code. And and order of magnitude less admin time.
Those were measurable results. Here is my 'opinion' of why the differnces were so dramatic.
I taught Win32 programming and system internals for four years. I was also chief scientist for Redmond Communications who publish a technical journal on Microsoft Software/strategies. So I am not a linux bigot.
My observation has been, that no one truly understands the internals of a windows system. Just as I start to get a handle on the latest caching, memory management, threading issues, there is an 'upgrade' via some patch that changes many of the internals. In addition, as shown by the above threads, most windows sys admins seem to have vastly difference experience and understanding of how to configure and maintain systems.
Unlike most nerds, I will not blame the admin, but blame the system. In the scientific community, windows, in practice, has proven to be somewhat opaque.
Unix, on the other hand, is incredibly well documented and all source is available. Uncertain how inodes are locked and released? No problem, there are many books and references to help you. If worst comes to worst, crack open the damn code.
This has nothing to do with open source, but more to do with the which communities evolved the techonlogy and the underlying motivations of companies hawking their wares.
Note, this is not a good thing, or a bad thing it is only a thing.
There were many people out there criticizing the studies accuracy. I must say I do not have a single colleague that I have spoken with that doubts its varisity from personal experience on BOTH sides of the isle. I just knew that I had to share my own experience with you. My only doubt about the story is that I would say 'order of magnitude' for production servers.
Thank you for your time,

Even though I'm not a heavy scripter my story follows:
I used NT/IIS 4.0 for several years switching to 2000/IIS 5.0 when it was available. I have a small business and primarily use my websites for testing solutions that are implemented for my clients and for e-mail. That being said I had to check my servers daily for hacks and patches and got rooted several times. After switching (sorry Apple) to Linux I've been rooted 1 time (my fault for leaving a known bug open via ftp). Going from checking daily (sometimes 3 to 4 times a day) and still getting hacked, to checking weekly (unless I notice an article here a la openSSL, etc.). My TCO is dramatically less. It has also allowed me to confidently recommend Linux solutions at my full time job.
Time is $$$ and the less I spend trying to avoid script kiddies the more time I have to do real work and get paid.
Scripting is close to the true reason linux admin takes less effort.
With linux the admin's education is never limited because everything is open to inspection. With windows the admin's education is limited to what M$ wants them to know. Thus severly handicapping their diagnostic abilities and their intuition.
This effectively reduces the effect of eXPerience for the windows admin. A 5 year windows vet will likely be no smarter than a 3 year vet. However, a 5 year linux vet has every opportunity to exceed his 3 year counterpart.
