This is Salesforce.com view of What is Cloud Computing?
Running business applications needs: Datacentres, Office Space, Power, Cooling, Bandwidth, Networks, Servers & Storage; Complicated Software Stack and a team of experts to install, configure & run them all. Development, Testing, Staging & Fail over environments.
All this takes valuable IT & business resources to manage. True Cloud providers (beware the false cloud) mange all of this for businesses like yours so your business can worry about the important things, i.e. configuring it for your business processes and growing your business.
Cloud computing enables business to plugin and start using the software products on a pay as you go basis, this changes the financial justification from a Capital Expense to an Operational expense and also means you can start you project in minutes not months.
There is so much more to add but I will close by saying “Don’t be scared of the Cloud, embrace it; at least keep your eye on the horizon because Cloud Computing is growing and it is NOT a Storm Cloud.”
