Enterprise software marketeer Christian Horak has been having fun with his Twitter network investigating whether it's possible to encapsulate "Cloud Computing" for the layman within Twitter's stringent 140-character limit.

Responses so far include one from JP Morgenthal ("Cloud computing is...The big rental station in the sky") and another from Suresh Ramakrishnan ("Wherever you go, there your applications are!").

Sun's Chief Identity Solution Architect, Mark Dixon, came up with the very comprehensive "Cloud computing provides application, database, platform, storage, and computing services in a virtualized utility to enable agile business" while SAP Platform Adviser Darren Crowder defined Cloud Computing succinctly as "A cost effective hosted platform that provisions business software capabilities on demand e.g. like electricity or water."
