Two books on changing the "how"
In my role I have the great privilege to get to speak to a lot of really interesting people and companies that are on their Cloud journey. The bits and bytes of Cloud are not that hard for most technologists and companies, the hard part is the cultural change.
For a long time I have been recommending that people read the book, "The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win" by Gene Kim, Kevin Behr & George Spafford. You can get it on Kindle for under $10 and you can read it in a weekend.
