OpenStack and the Future of Cloud Computing with John Purrier

john-purrier

“Why do we need any open source versions of proprietary implementations? I would argue that first of all, it’s just good for industry and the ecosystem.”

Cloud service providers like Amazon, Google, and Microsoft provide both infrastructure as a service and platform as a service. Infrastructure as a service gives developers access to virtual machines, servers, and network infrastructure. Platform as a service is the software that runs on top of that infrastructure as a service–this includes things like Amazon DynamoDB, Microsoft Azure Machine Learning, and Google App Engine.

OpenStack is an open-source cloud operating system. Today’s guest is John Purrier, a founder of OpenStack and the CTO of Automic Software.
