This document discusses the future of cloud computing and whether an open source future is inevitable. It outlines the different types of cloud computing including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). While open source technologies like OpenStack are gaining popularity, the future of open source in the cloud is uncertain as proprietary vendors have financial incentives to lock in customers and make switching costs high. An open future will need continued support and involvement from advocates to help preserve open options.
