A quick and comprehensive guide on devops! While, as a devops engineer (haha if you read the book, you'd get the joke) for many years, i do know much of this already, there's always something new! This is not a book that says, use these tools and you'll be doing devops in no time, because such a toolset does not exist. But it's full of wise advice. Particularly the pitfalls described in the latter chapter, that stuff happens even in companies that are trying to do devops. Highly recommended!!
