I would argue that everyone wants this for the wrong reasons. Then I would argue that most production environments don't need it. Unfortunately I do not have numbers but my rough estimation is that average application is maybe 10k users. Where my mobile phone would be overkill to host such application. My estimation is based on that most of the web-apps are not even close to Alexa top 500 - where top 50 is insane and they need scalability and availability - where I expect amount of people visiting sites is governed by "power law" so those top 50 get 80% of traffic and the rest gets 20%. Don't even start on all those intranet applications that are having maybe 100 to 500 users at all and I would expect there are much more of that kind of applications in the world than there is google search engines :)
