As says might remember. From what I remember SaaS didn’t turn up by itself. The grid and utility people started with IaaS in the early 2000s; by 06 IaaS-PaaS-SaaS constructs appeared in explanations of “cloud computing”. By late 06 I was using them in papers at BT.

... it should be noted that "utility" was silent i.e. "as a [utility] service". Concepts of compute as a utility date back to 1960s - Parkhill, McCarthy etc. The utility aspect was a distinction from earlier ASP models which were more "as a [rental] service".

Gosh, just read the wikipedia page. Quite painful. Open Source with SaaS / FaaS (an early term for PaaS) / HaaS (an early term for IaaS) was part of my OSCON keynote in 2007 ... oh, that reminds me. PaaS really didn't start to appear until mid 2007. It was floating about.

Simon, SaaS was common-ish parlance by late 2006 and we were using it in board papers at BT by then. When I met you at your then offices on the river near Parliament (were you with canonical then?) we spoke about the old-wine-new-bottles aspect of all that.

Oh, agreed ... SaaS & HaaS was, the post I mention is March 2006. But I have the sneaky impression that PaaS appeared mid / late 2007. My memory might be faulty. Certainly I used FaaS before then (Framework as a Service) but PaaS ... well, it was sometime around 2006 /07.

Anyway, the real question is ... why care? The most important part is most missed the whole utility aspect, confused it with ASP, didn't understand the gameplay (i.e. ILC) or their inertia and hopeless giants with all the advantage lost their future to a chap called Bezos.
