Cloud computing is a popular phrase that can have a thousand different meanings. In a nutshell, cloud computing is a way of delivering IT solutions to businesses in a way that is scalable and affordable. SomethingCool.com offers several solutions as part of The Cloud, including Email and Collaboration, Hosted VoIP, Hosted Computing and Backup and Disaster Recovery.
The Cloud can take the form of a private cloud, where everything is owned by the company. A public cloud, where everything is accessible across the Internet (hopefully, securely), or a hybrid cloud, which is a combination of both.
