The Sheep has been ferreting around for some more useful information for you.
For a small and medium size business (SMB), the benefits of cloud computing is currently being driven by adopting the technology. In the SMB sector there is more likely to be a lack of time and financial resources to purchase, deploy and maintain an infrastructure (e.g. the software, or the server and associated storage).
In cloud computing, small businesses can access these resources using an Internet connection and Web browser. They can expand (or shrink) services as their business needs change. The pay-as-you-go subscription model is designed to let SMBs easily add or remove services and you will typically only pay for what you use.
A good example of this would be the cloud facility known as Drop Box, which offers a subscription service for on-line (cloud based) data storage. Here at Busy Sheep, we make full use of Drop Box to maintain backups of all the web sites we administer.
