This is a free report that you can download from O’Reilly’s website. It deals with how DevOps was adopted to facilitate Nordstrom and Texas.gov (with a glimpse of how the Texas.gov CISO inserted security provisioning in the development processes).
If you’ve read The Phoenix Project and felt that OK this is nice, but it is also a novel, the Nordstrom story is an indication of how to adapt this outside a novel concept and into the real world. It is worth your time, especially in cases when you need to appeal to real world examples.
