Cloud why now?

I wrote and published a paper, called Cloud why now? on the Knowledge Transfer Network site. How new is Cloud Computing? It is a clear evolution if two trends in IT architecture that have had an immense and limited success. The successful trend is distributed computing and the less successful one utility computing. What is driving this evolution and why now? This article has a quick look at the trends that have brought this to this point and looks at the fact that like most economic revolutions, it’s a confluence of both socio/economics and science. The article concludes by looking at the paradox of data, to see how it is both a driver of change, and an inhibitor.

The paper was originally published in December 2009, this article was posted in May 2015.


  1. The file was hosted on my linkedin profile. It remains a dense, and maybe self indulgent read. It’s now seven and a half years old, much of this has aged well, yet some of it has aged not so well.

  2. I had read Jim Gray’s paper but not seen how the economics and physics of fibre vs. copper would begin to impact distributed systems design.
