Corporate Cloud Computing: Is it Worth the Money and the Risks?

Most people use cloud computing in different ways, but rarely give it much thought. On smartphones they listen to music that is stored "in the cloud," and on tablets they read books and magazines that are also stored there. If they use Gmail or Hotmail, they're using a cloud-based email system. One reason most users give the cloud so little thought is that these cloud services work well and are free of charge.

Most business users, however, give the cloud serious thought because they use it for professional purposes, and, crucially, they pay a lot to do so. Companies use cloud computing for three principal purposes: data storage, security backup and disaster recovery, and online applications. Let's examine each, and then look at the risks.
