I’ve been keeping up with private clouds. I’m not doing too much private cloud work, but I am writing and designing courses on the topic. As you may recall, not long ago private clouds were the primary focus for most enterprises. They did not want their data and processes out of their direct physical control, but they did want to move to “a cloud.” So they hosted their workloads on one of several private cloud operating systems that were being pushed at the time. Some proprietary, some open source.
