“OpenStack continues to gain mindshare among enterprise CIOs …….. We continue to
see OpenStack becoming the de facto open source option for deploying private
clouds. However, this will accelerate only after more OpenStack-trained developers
enter the workforce…..” [The 451Research Take (https://451research.com/openstack)]
OpenStack engineers make 36%
more than other cloud engineers.
