OpenStack Community Snapshot24
OpenStack Mission“To produce the ubiquitous opensource cloud computing platform thatwill meet the needs of public andprivate cloud providers regardless ofsize, by being simple to implementand massively scalable.”
Why is OpenStack important? Open eliminates vendor lock-in Working together, we all go faster Freedom to federate, or move between clouds
OpenStack Founding Principles Apache 2.0 license (OSI), no paid ‘enterprise’ version Open design process, 2x year public Design Summits Publicly available source code repository All community processes documented and transparent Commitment to drive and adopt open standards Modular design for deployment flexibility via APIs
