expect FUDD from Microsoft dupes
The response to my comment from Anonymous Coward, saying "Linux is cheap. That's why." does not address, nor could that person or any other Microsofty address the Unix/Linux adoptions reasons over Microsoft indicated in my comment.
For example - Anonymous Coward, how do you address "facts" of Cern, and NASDAQ, NY Stock Exchange, London Stock Exchange, Cern, Top 500 testing results that "officially" have reported Windows Server less reliably, less scalable, Les Secure and less powerful than their ultimate preference of Linux or *BSD (UNIX)?
Another tidbit of technical information for Anonymous Coward:
Microsoft wished at one pointto "license" the ZFS file system from Oracle for their new "resilient" ResFS Windows 2012 . Why? Because ZFS (and Linux "BtrFS" file system) have functionality not available in Windows software - like very robust large Data Files "storage pools", drive hot swapping and backup, very sophisticated Cyclic Redundancy Data File Checking and other advanced modern features that are either completely absent in new Windows ResFile system and/or are severely limited or not robust as compared to Oracle ZFS. In the end, they could not license and therefore use these technologies since ZFS license Open Source which restricts or prohibits use by software license and policies of companies like Microsoft.
This, and other facts quoted in my comment have absolutely nothing what-so-ever to do with "cheap" or low cost or free, but everything to do with world class functionality, great performance (a la Top500), exceptional stability (a la Cern Particle Pysics laboratories) of UNIX/Linux.
Cloud services like Amazon EC2, Eucalyptus and OpenStack Cloud (collectively comprising about 90 plus percent of major Public and hybrid Cloud Services) have been "tested" to provide greater reliability, security and scalability than Windows 2012 based V-sphere Cloud serviices.
Please provide a sane, "factual" (very important) and technically accurate response if posting.
Those that cannot face or accept reality are doomed to live in confusion and ignorance.
