Nebula looks to democratize cloud computing with open source hardware: "As people face this industrial revolution of big data, they can't use Oracle anymore," said Kemp in an interview at OSCON. "It doesn't scale. We want to be the platform that enables that. We really believe that, if all of this stuff will achieve its potential, in being open, it will reshape the core of computing. We really think there's this new paradigm of computing where people are building on top of infrastructure services instead of infrastructure."
