What operating system do you run Joomla! ? I will refer to the operating system in this blog as a platform.  Due the Open Software that Joomla is built on (Apache, MySql, PHP) Joomla! can run on various platforms.  The Joomla! 1.5 installation manual indicates that Joomla has been tested on Windows, Linux, and Apple Mac OSX.

I would say that 99% of the people I talk to run Joomla! on the Linux platform.  I recommend the Linux platform to the majority of the folks who ask for advise.  I am not suggesting that windows and OSX is less suited. It really depends upon each persons or companies circumstances.  For example, budgets, security, transaction volume, experience, skills, company policy, etc.  

I am a long time IT professional in large data centers.  For over 25 years I have been a systems programmer on mainframes and morphed into UNIX administration on IBM's flavor of UNIX called AIX on IBM Pseries enterprise servers (Power5 and Power6).  

Is Joomla! ready for the corporate world?  I believe it can be when used where it makes sense.  

I decided to challenge myself with the task to install Joomla! on an IBM Pseries Server inside a VIO LPAR running on the AIX Operating system.   
Yesterday I accomplished this goal.  After installing AMP (Apache, MySQL, PHP) I was able to install Joomla! 1.5.6 without any difficulty.

I hope to use this Joomla! installation for our teams documentation.
For those interested more in the advantages of the IBM Pseries servers take a look at a demo of only two of the benefits of a Power6 server...
