One of the negative reviews did have a good point, that this essay comes off as a bit of a rant. But then why shouldn't it? Dealing with IT Operations, historically speaking, is usually a pain in the SCSI port. The real value being provided here isn't so much in telling you what DevOps is (which, to be honest, the subject is almost glossed over and only the main talking points are mentioned). No, the value is in telling you *why* DevOps was an inevitability, what purpose it serves today and what it is fixing.

If you read this and find yourself nodding your head, commiserating with the pain described by the author, maybe your shop is a candidate for a DevOps cultural transformation. And really, that's what it is, a cultural transformation. The technology is all for naught without it.

I'm reading this from the perspective of an operations team leader, and of someone successfully affecting a DevOps business transformation in a software development shop.

I didn't think I would like this book. I mean who wants to read about work life at home. LOL
I live this stuff every day, but as a manager it did give me a different perspective on the DevOps movement.

I downloaded this book to see what all the hype about DevOps is about. Like other reviews of this material have stated, this Ebook isn't an in-depth look at how to achieve a DevOps environment or how they work at a functional level. Instead it is about what DevOps is at a 1000 foot level but what the book provides is an eye opening mindset that Operations is shifting and the cloud and virtualization is driving it.

This book made me realize that within the next five to ten years Systems and Network administration is going to completely change from fighting individual fires to the automation of deploying and maintaining thousands of virtual servers and network instances via private and/or public clouds.

I am a system administrator and I have been one since the 1990's. The way my job was and still is now is going to change from custom individually installed servers or VM's to push button automation of thousands of virtual machines with the identical software running on them all. The things I thought that would make the cloud unusable for financial and other companies with high security demands are not going to matter at some point.

Good information, the book made me feel like I am becoming George Jetson where I will eventually just sit at a terminal pushing buttons to kill a misbehaving virtual machine and then hit another button to deploy a new one!

While there is some interesting insight shared in this ebook it reads more like an insider rant than a document intended to educate. It's too short to be of any use to someone needing to learn about operations in-depth and much of the content is subjective although as with so much of IT there are frequently multiple solutions to a given problem. Determining which one is "best" sometimes depends on finding out in advance what your boss' preferences are!

O'Reilly produces some useful (and short) ebook reports that help clarify and educate those of us in the tech industry. I just finished What is DevOps? - Infrastructure as Code by Mike Loukides, and it fits squarely in that "short ebook" category. In fact, you could make the argument that this is really a long blog post instead of an ebook, since it's only around 16 pages. But when the price is free, why quibble over semantics?

Loukides makes the argument that the NoOps movement is a misnomer. The function of Operations in a company such as Netflix or Amazon still continues to exist regardless of what might be inferred otherwise. The more relevant question is centered around what Operations actually means in the current technology state. Loukides states that the Operations team and the Development team become more closely allied, so that applications can take full advantage of PaaS (Platform as a Service). This adds redundancy and resiliency as core elements of an application, as opposed to just tossing the application over the fence for someone else to worry about if something goes wrong.

What Is DevOps? is by no means an exhaustive examination of the DevOps topic. At 16 pages, it's barely enough to get started. However, it *is* enough to get you thinking in the right direction, and provides the start of a framework for you to "know what you don't know". It's worth the few minutes (and no cost) to download and read.

Did I miss something in the description? I don't recall seeing anything stating this "book" was only about 10 pages of high-level summary and fluff -- with an obvious intent to get the reader to pay extra for an upgrade! Yes, it's free, but that doesn't make it right.

When I found this I was really happy - a book just what I was looking for - and free too! After downloading and reading a few pages i thought its going to be a great book, but then it stopped. Its basically a blog post - you can even find online on O'Reilly Radar- takes four pages when printed out.

So its worth reading, but as a book its too small to learn anything useful.
