In a previous post, “What The Heck Is Cloud Computing?” I broke the cloud up into three categories. however I do not think I did a good job of delineating these categories with examples. So here goes:
IaaS: Infrastructure as a Service
PaaS: Platform as a Service
SaaS: Software as a Service
And thanks to a heads-up from Dare Obasanjo, I found a somewhat different labeling of the cloud from Tim O'Reilly in his blog post Web 2.0 and Cloud Computing. His breakdown is:
Platform as a Service
Cloud-based end-user applications
where these labels pretty much correspond 1 to 1 to the ones above.
I hope this clarifies things a bit.
