One of the areas on which we reached clear agreement in the G-Cloud and App Store phase 2 was the definition the layers of the stack, infrastructure, platform and software, and their corresponding scalable, standardised counterparts: infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS). Pleasingly, our delinations were very similar to prior work from two decades ago by IBM, except that ours incorporate virtualisation.
Following my involvement with the UK Cabinet Office’s G-Cloud and App Store programme I’m updating my definition of Cloud Computing, and also incorporating the NIST definition. My answer is “Cloud = Grid + (Utility * N)”, and here is how I arrived there…

People keep going around and around in circles on the debate of whether you should replace servers and desktops sooner rather than later when you take into account the improvements in energy efficiency in recent years combined with the embedded energy cost of manufacture of computers. So, I decided to get out my calculator and [...]
We recently became the first UK Web host to be Carbon Neutral accredited, but does it actually make a real difference? In fact, are we going about all this wholesome planet-saving the right way at all? As an aside, our arch-rivals over at RackSpace claimed they were the first UK Web host to be carbon [...]
There is such a thing as a free lunch, and it is called open sauce software! Er, open source even. Did I forget breakfast again? Anyway! I am constantly surprised that, despite its massive and growing use in many areas, open source software solutions, and the benefits therein, are either unknown or shunned even by [...]
