“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. Questions  What is Infrastructure-as-a-Service (IaaS)? Why do we need an open source cloud operating system? The hypervisors managed by OpenStack can be different, but the user has a consistent interface – why is this advantageous? How much more efficient are containers when compared to virtual machines? What is the difference between scalability and elasticity? Why is shared state dangerous? How do you manage to test a system like OpenStack? How will OpenStack, AWS and other cloud platforms evolve going into the future? Are we headed towards a polyglot cloud world?
