I had this book lying on my shelf for multiple years and couldn't read it for such a long time as reading it didn't look like a fun activity. Although it can be called procrastination, I was right postponing opening this book for years.
Although it's been issued just 5 years ago it's completely outdated now. Not so much if you weren't following the latest trends in tech.
This book looks like a shy attempt to cover what was new and groundbreaking back then but neither did the author knew what he was trying to teach the audience nor did he have a practical experience in most of the concepts described.
After all these years this book looks like a repetition of what was covered in "Release it" and "DevOps Handbook". That's the price you have to pay when you focus on what was new while the author was writing the book and became obsolete now. I would love to have this book if it was much smaller in size and focused more on the concepts and patterns rather than on technologies and what was on the bleeding edge back then and couldn't stand the test of time
My score 2/5
