On Friday, during our cloud computing event, Whose Cloud Is It Anyway?, Charles River Ventures partner George Zachary noted, "The cloud is the new dotcom." He was one of the judges for the demo startups, and for good or for bad, he might be right. Cloud computing as a term is broad enough to encompass most internet startups and already is in danger of being latched onto as the next catch-all category. Yet there is also obviously something there. Amazon, Salesforce, Google, Microsoft, and even Facebook all want to become the cloud platform of choice for startups and developers to build their Web apps on.

And we are already seeing some impressive cloud-based apps that would have been much more difficult to build without these platforms. During the demos, for instance, Veodia showed an app for recording video in the cloud straight from a laptop’s camera—no uploading required. FathomDB is putting a relational database in the cloud (on Amazon’s EC2), and Diomede Storage is offering its own cloud service with a twist: online storage where you can monitor the power consumption of each file and act accordingly.
