The survey summarizes responses from 822 OpenStack users regarding their deployments, usage, and experiences. Key findings include: the majority of respondents were from the US, India, and China; most worked in information technology at large companies; and private on-premise clouds were more common than public clouds. The majority utilized the OpenStack Compute, Image, and Dashboard services and deployed OpenStack on Ubuntu and CentOS using tools like Puppet, Chef, and DevStack.
