The document summarizes the results of an OpenStack user survey conducted in spring 2014. It provides data on deployment details like the number of deployments by country, organization size, industries using OpenStack, deployment stages, and hardware and software configurations. Key findings include the US having the most deployments, avoidance of vendor lock-in being a top business driver, and Ubuntu and CentOS being most popular operating systems.

COMMENTS

24. Over the last 6 months I think the documentation
has improved significantly. I have seen others
recently hold up OpenStack docs as a model to
strive for.
MY FAVORITE COMMENT

25. • Community
• Open Source
• Flexibility
• Extendible

WHAT PEOPLE LIKED ABOUT OPENSTACK

26. • Channel operations needs to development and companies
• Arrange regular feedback from user groups and ambassadors
• Close the gap for Enterprise IT
• Industry specific working groups
• Focus on those consuming OpenStack
• Expand training and certification marketplace
• Define what OpenStack is
• Improve/replace Launchpad
USER COMMITTEE/FOUNDATION PRIORITIES

27. • Stability of core should be a priority above adding new functions
• Add how-to guides, problem management documentation, expire old
documentation, end user guide (but much less than previous surveys)
• Zero downtime migrations
• Installation and configuration (but much less than previous surveys)
• Cross Project consistency with APIs, SDKs and CLIs
• High availabilityVMs
• Neutron stability, simplification, resilience, IPv6 and scalability
• Improved function and usability in Horizon
• Security, auditing (but much less than previous survey)
• AWS/EC2 compatibility
FOCUS FOR FURTHER ENHANCEMENTS

28. • Mid-cycle gathering of operators
• At eBay in San Jose – Thanks Subbu
• Moderated by Sean Roberts and Tom Fifield
• 50+ attendees
• Take-away
• Very positive atmosphere – no tranquilizers needed
• Operators want to get involved early – Blueprint-on-blueprints
• Many volunteers to help ‘outside of the day job of running OpenStack clouds’
• Lots of ideas for the summit
• Aim to repeat in August/September 2014
• ‘Brief’ summary at https://etherpad.openstack.org/p/operators-
