What constitutes "cloud computing" is fiercely debated, but I define cloud computing as using software and/or data storage that is located remotely and that is accessed via an Internet connection, rather than using computers in your offices or remote computers you own and access by a dedicated transmission line.
Here are some popular types of cloud computing:
"Software as a service" ("SaaS" in geekspeak): Using, over the Web, a software program that is owned and hosted by someone else (Google Docs, for example).
Software hosting: Having a cloud provider host at its facilities some or all of the software you have purchased the right to use ("licensed" in lawyer-speak) and would otherwise run on your own computers, except that you now use that software remotely via a Web connection.
Online backup: Using a remote service to periodically back up the data stored on computers on your premises.
The biggest issues businesses contemplating moving to the cloud need to understand are the breadth of the contract-negotiation task and how that impacts the cost-benefit analysis.
