Have we entered the age of NoOps infrastructures? Hardly. Old-style system administrators may be disappearing in the face of automation and cloud computing, but operations have become more significant than ever. As this O’Reilly Radar Report explains, we’re moving into a more complex arrangement known as "DevOps."

Mike Loukides, O’Reilly’s VP of Content Strategy, provides an incisive look into this new world of operations, where IT specialists are becoming part of the development team. In an environment with thousands of servers, these specialists now write the code that maintains the infrastructure. Even applications that run in the cloud have to be resilient and fault tolerant, need to be monitored, and must adjust to huge swings in load. That was underscored by Amazon’s EBS outage last year.

From the discussions at O’Reilly’s Velocity Conference, it’s evident that many operations specialists are quickly adapting to the DevOps reality. But as a whole, the industry has just scratched the surface. This report tells you why.

If you’re going to do operations reliably, you need to make it reproducible and programmatic.

It doesn’t matter whether the nodes are in your own data center, in a hosting facility, or in a public cloud. If you’re not writing software to manage them, you’re not surviving.

Optimizing how tasks are distributed between these facilities isn’t simple; that is the province of operations groups. Developing applications that can run effectively in a hybrid environment: that’s the responsibility of developers, with healthy cooperation with an operations team.

Mind provoking material about the state of IT operations.

Reviewed in the United States 🇺🇸 on August 6, 2013

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!

Should have been titled "Why is DevOps?"

Reviewed in the United States 🇺🇸 on January 9, 2013

Verified Purchase

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.

Great if brief summary

Reviewed in the United States 🇺🇸 on July 29, 2016

Verified Purchase

This brief text might well have been a blog post. It does succinctly describe the evolution of computer development and operations, and contrasts practices in the 80's and earlier with those now. These changes, which the author attributes primarily to massive increases in scale of server and network resources, and the availability of flexible deployment
options via the internet, mandates the collaboration between developers and operators, that describes Devops. It's a logical thesis that correctly I think predicts the new direction in software development and infrastructure deployment.

Very generalized, short, and out of date

Reviewed in the United States 🇺🇸 on April 27, 2017

Verified Purchase

"As applications move to the cloud, operations become a software configuration and coding task rather than a hardware management task." That summary of the book could save you 15 minutes (which is how long it took me to read it). Loukides has a nice writing style, but his observations are so general and detail-free that you are unlikely to benefit much.

He also says pretty much nothing about how devOps is built on lean practices, which is a curious omission for an essay that purports to summarize the subject.

Perhaps in 2012 the book might have been worth 3 stars, but given its obvious age in a fast-moving field, few can benefit from reading it. If you know nothing about the subject and want to spend just 15 minutes on it before moving on with the rest of your life, it might be worth your time. Otherwise, take a pass.

Not that focus on today's

For me it felt like the author put more effort explaining how things were done in the past than elaborate on current practices, methods in IT culture now days.

Good a san introduction

Reviewed in the United States 🇺🇸 on January 21, 2018

If you have no idea about DevOps, this is the book for you. A fairly good short and contextual introduction based on the history of traditional it ops and development organizations and processes.

Reviewed in the United States 🇺🇸 on November 8, 2014

Verified Purchase

Great read if you are a developer who needs to learn the fascinating history of Dev Ops. The individual who is new to the concept may not be able to describe exactly what a dev ops engineer does and when are they needed in a project.
All things considered this is a great book and a great read.

Bit of a tough read but honest

Reviewed in the United Kingdom 🇬🇧 on December 7, 2017

Verified Purchase

Devops is an interesting area but is also subject to overzealous managers thinking is the latest silver bullet to help their company grow.

This book is really more of a paper with no real recommendation. The title does suggest it's a definition but I'd expect some examples, esp of non web applications

StuBaines

Easy too read by captures the key points

Reviewed in the United Kingdom 🇬🇧 on June 29, 2015

Verified Purchase

Short and concise this e book provides some direction for those looking to define DevOps in their organisation. Perhaps that should be "how to operate differently" rather than define DevOps.
Use as a level setting tool before starting the discussion; this is a positive view on the changes (apart from BOFH who clearly deserve what is coming!)

Finally a definitive guide to differentiating on premises silos approach and attitudes against DevOps collaborative approach. If you're an on prem engineer looking to understand the ethos behind the term DevOps this book is well worth an hour's read

A good introduction to the world of DevOps. Would highly recommend reading the Phoenix Project as the next DevOps book, as it brings this world to life.

A short but succinct 18 page overview of the history and reason for devops, particularly for system administrators, without too many acronyms or technical terms.
