"There are a few definitions of Cloud computing floating around.  At Robust Tech, cloud computing means we do everything for you and publish it all to our "cloud" (aka, our internet web servers).  This means you don't need software, hardware, or anything other than an internet connection.  All you need is a device (pc, laptop, tablet, pda, smart phone, etc) with an internet connection."

Cloud computing is Internet-based ("cloud") development and use of computer technology ("computing"). The cloud is a metaphor for the Internet, based on how it is depicted in computer network diagrams.

In simple to understand terms, it is a way for users to access technology-enabled services from the Internet ("in the cloud") without having to understand the technology behind it, and without having in place any infrastructure other than a common internet connection.

This allows businesses, large and small to conduct their business as usual and take advantage of technology and the internet without having to spend thousands of dollars for a web server, infrastructure and expertise to manage to support it.

All you need is an "internet client" which can be a home computer, desktop, entertainment centers, tablet computers, laptops, notebooks, wall computers, handheld's, sensors, monitors, etc.

Cloud computing is a general concept that incorporates software as a service (SaaS), Web 2.0 and other recent, well-known technology trends, in which the common theme is reliance on the Internet for satisfying the computing needs of the users. For example, Google Apps provides common business applications online that are accessed from a web browser, while the software and data are stored on the servers.
