Google Apps 5 Years After, 2009 - 2014. A Practical Definition of Cloud. There’s the NIST definition of cloud (PDF)—or, as they call it, “cloud computing” (this post explains why I don’t use “computing”). And I have also offered up my own definition: Cloud is a system where users acquire and manage technology resources on their own while the owners of those resources still maintain control of them. Whether you like mine or not, I think these two definitions offer nice book-ends: NIST’s is technical, and mine is conceptual. But neither is practical, though NIST gets closer than I do. What I mean by this is that, if you want to try to figure out whether cloud is the right model for a particular purpose, you need a definition of cloud that you can apply to that purpose to show the costs and benefits in measurable ways.
Conceptual definitions won’t do that at all. NIST’s technical definition of cloud has the right components.
