Never mind the naysayers: Del Monte Foods is a big believer in cloud technology. In just three years, the $3.7bn company has placed its entire inbound supply chain in the cloud. The result, according to senior manager of global trade compliance Brian White, has been tighter relationships with suppliers, and greater visibility of product in the pipeline.

What is this thing called "cloud computing"? It's nothing new - that much is certain. Software vendors have been offering applications "hosted" off-site for years. The idea of computer services as a kind of managed utility dates back to the 1960s at least. Salesforce.com, founded in 1999, based its entire business model on the cloud, even if it didn't use the word at the time. Since then, we've seen a variety of takes on what came to be known as Software as a Service, or SaaS. That's now been supplanted by "the cloud," a term which refers to any number of apps that reside in huge banks of servers located far from the client.
