I’ve just finished a Continuous delivery book. I must say, that my expectations were much higher than the level at which the topic was described. I do not say, that this is a bad book, but having a few well-grounded articles, like Fowler’s I simply do not find it good enough for a deep dive into the problem’s space. The last chapters present a way in which the whole book should have been written: simple cases with a short explanation dealing with the most common problems. From the other side, the very first chapters repeat like some kind of mantra the same sentences paraphrised over and over again (automate your build, do nothing manually, etc.).
If you’re a noob, and read nothing about this topic, that’s a very good choice. For the others: it is not a must-have.
