Cloud Adoption Roadmap: How do you make the choice between SaaS, PaaS and IaaS?

I've been extremely busy at the office the last couple of weeks fire-fighting infrastructure delivery issues. There were quite a number of times, I wished I could fast-forward to the future and switch on the whole production environment on Amazon Web Services instead of entering yet another painful procure and install saga. Anyhow, I'm back here to spend a few precious moments of my so-called spare-time to pick up on one of the five questions posed a couple posts ago.

3) How do you make the choice between SaaS, PaaS and Iaas?

My first response on receiving this question was that it (the question) was obviously "wrong". SaaS, PaaS and IaaS are technology categories that can be useful for discussing the solutions available. However, these are not binary (or should I say ternary) choices and our clients are often going to adopt solutions across all these categories.

On further thinking, I think the question behind this that we are all trying to grapple with is how to figure out the best roadmap to the cloud future. Let's spend just a few moments working this one.
