However, a notable minority—some 15%—occupy C-level or executive roles. It encompasses private clouds, the IaaS cloud—also host to virtual private clouds (VPC)—and the PaaS and SaaS clouds. In our analysis of user activity on the O’Reilly learning platform , we found that DevOps-related search and usage declined in both 2018 and 2019.
