“If computers of the kind I have advocated become the computers of the future, then computing may someday be organized as a public utility just as the telephone system is a public utility... The computer utility could become the basis of a new and important industry.”

John McCarthy - 1961
Cloud Computing“Large computers were going to be replaced by networks of small ones capable of communicating with one another and with common databases that might be on computers of any size. (...) Also, any user at any node could access data on any database in the network with the same provisos.”

DevOps, NoOps... What it has to do
with cloud?
• Gazillion rollouts every hour/minute/day/second• Full access to everyone• No control at all• “I went to a conference and saw that cool guy saying that this is the way to do it”
