OpenStack has emerged as a preferred open-source cloud management platform based on its openness, interoperability, flexibility and large highly active community of users, developers and vendors. It has also established itself as the platform of choice for NFV workloads. According to the most recent OpenStack Foundation global survey, Ubuntu is the most popular host and guest operating system for OpenStack, with more than half of all OpenStack instances running Ubuntu, and 70 percent of the Public Cloud Guest operating system market.
