In typical cloud computing, users connect to a powerful, centralized data center. But Cappos's cloud is less of a dense thunderhead and more of a fog. His system, called Seattle, connects devices directly to one another in a decentralized network, relaying information more quickly than it could through a single, often distant exchange point. "It lets you use a little bit of disk storage, network, memory, and CPU in an isolated, safe way," he says. Because Seattle allows users to access the Net with foreign IP addresses, it enables developers to view their sites or apps as they would in other countries. That ability is also particularly valuable to individuals who wish to circumvent local censorship.
