This remains one of the most important books software engineers can read. The second edition is even better than the first, updated to fix a lot of the "outdated" criticisms the first book gets, incorporating the modern DevOps movement, microservices, and modern technologies used in software engineering.

I really just can't say enough about this book. It's required reading. If you're responsible for code that runs on networked production systems, failing to read this book should be a fireable off

You're wasting time reading this review, you could be reading this book instead.

Release It! is one of the most important books I think programmers can read, easily as important as the oft-cited classics like The Pragmatic Programmer or the GoF book. Release It! isn't about writing super-spiffy code, or object-oriented design, but it should drastically affect how professional programmers write their code. It focuses on what engineers need to do to get their software into a state where it can actu

I need to start by saying that this is one of the best technical books I have ever read. To me, it's easily as enjoyable and useful as Code Complete, The Pragmatic Programmer, or The Mythical Man Month. If you're a sysadmin, an architect, or a developer that works with medium-to-large-sized systems, then do the following:

1. Stop reading this post
2. Order this book from your library or buy it from The Pragmatic Programmer's web site

If you're in the business of designing, building, and operating complex and distributed software systems that serve online customers via web and mobile interfaces, systems that span many different technological components and have strict operational constraints, systems that might be stressed because of unpredictable and sometimes massive spikes in online requests, then this book is very good and highly recommended: it presents a no-nonsense overall approach.

There's a relatively short list of books I would like to keep on my desk. Most often those books are references and a composition of famous quotes. After I've read this chap I'd like to have it on my work desk at any moment.

This book is a perfect mix of lots of useful technical insights, practices and recommendations got from the author's hard-earned experience combined with some of the soft-skills you need to make your software and its maintenance (which as the author states costs more than the

It's on overview of how systems break in production and how to avoid it. The author manages to take a pretty dry subject and produce a book that is very easy to read.

Now, it's pretty dated in a few places. It's from 2007, when the term DevOps wasn't even widely used yet. At the same time it's interesting to see how a lot of it still holds.

There are too many references to JVM-speficic issues. I don't think this ruins the experience for readers working outside the JVM, but it's strange seeing cas

This book is a battle proven must read for any software engineer. Even after 7 years since the book has been published, pretty much every advice in it remains valid and relevant. The idea of the operations database has found market confirmation in products like Splunk. The Curcuit Breaker pattern has ever since been implemented numerous times in various OSS libraries.

A seasoned developer would have probably been learned some of the advice the hard way. Nonetheless I've picked up a lot of wisdom

This book is an incredible introduction to creating and maintaining resilient web applications in realistic, chaotic environments. This book has changed how I approach development more than any other. Every developer with something in production should read it.
Zbyszek Sokolowski
Great book showing different aspects and clues of delivering software to production. Many software architects are "short sighted" and thinks about make a software which passes unit/integration tests and are failing shortly after release books describes such cases shows good approaches and different ways to deal with the problem and testing like chaos monkey.


Armed with a thread dump, the application is an open book, if you know how to read it. You can deduce a great deal about applications
The original edition of this book introduced me to stability patterns and their evil twins, stability antipatterns. I've referenced its terminology countless times since reading it, especially Steady State, Circuit Breaker, and Fail Fast. I always include this on my list when newer developers ask what they should read. It's chock full of wisdom about distributed systems that no one bothers to teach you in school. The techniques here make the difference between code that will topple over at the s ...more

A stellar career in software engineering with all its hard-earned lessons packed into a single, easy-to-digest book. Release It! Is an essentially practical book that stems from the author's perceived lack of focus on developing software so that it runs in a production environments.

What would these kind of systems with a focus for real-world use look like? He starts by outlining stability anti-patterns. These are bad practices often found in the design of systems which render it more fragile, a

This book radically influenced the way I build and deploy software.

It's a whirlwind tour through designing code that behaves well in production, the many ways interaction between multiple systems can fail, deployment styles that avoid scheduled downtime, and case studies to demonstrate the surprises that happen in the real world.

For those new developing and deploying production software the pace might be hard to follow, but those with a bit of experience under their belt will find this triggers

I've been working on project that heavily used clouds and high availability for relatively short period of time but even that experience helped me to appreciate this book.

The book predates all the dev-ops hype, but still gives you tons of suggestions how to build a robust, scalable and easy-to-understand-when-something-goes-wrong application: think about failure, every possible component WILL fail in production. Every possible 'joint' like external system interaction will be broken. Every possib

To be honest, I've got something different than expected. What I was looking for was another 'Continuous Delivery' - a book about modern practices of shortening the delivery cycle, filled with examples / cases / ideas.

What this book is actually about is the overall quality of software products (looked at from very various perspectives) and how do different types of flaws impact the product / service in the end. As you can see, this is a far wider (& more generic) topic - if this is what you're l

Even almost seven years after publishing the book is a source of inspiration in designing production friendly software. I wish i could read the book three years ago. It would safe few sleepless nights to me and my colleagues. The book would deserve to being extend about e.g. Cloud, Software As A Service and even DevOps since they are key change drivers in release/deployment process nowadays. Anyway worth reading and thumbs up.

You can tell from the first use case the writer worked with big websites and using Java. Still, the book is full of useful advice on how to design software projects in terms in scalability, transparency, adaptability and ease of troubleshoot. I enjoyed the style - the examples are well chosen and the level of details is not to deep, just enough to explain why some decisions are better than the others and how to apply good judgement when needed.

This book is a rare gem. It is full of valuable insights and is written in a very good language. Which makes this book not only valuable source of information but also a pleasure to read.
I would set 10 starts rating out of 5 possible if I could.

Definetely recommend it to any software developer or system engineer.

It's a fantastic book about good software engineering from non-traditional viewpoints.

It takes another approach on good practices of software architecture: it considers more than just classic quality attributes, and it makes you think you to architect your system in a way that's not only reliable and with good quality, but also easy to operate with. Concepts such as evolutionary architecture, adaptable architecture are reivewed throughout the chapters on the last section. In particular I enjoyed
This was a discussion book at my current company. As a starting point for conversation, it worked well enough. It definitely had some challenges. Writing a software related book almost implies specific technologies. But specifying these technologies almost immediately makes the book out of date, as in this one. But only dealing in concepts makes the book impenetrable. But just rambling your way through chapters just makes it annoying. This book was uneven, but it championed better logging and me ...more

If you are in the business of making software systems, odds are that you might have heard about Nygard's book. People have raved about it since it was published in 2007.

That being the case, it had been on my to-read list for a while, but without any urgency. Then I went a conference where I heard two sessions with Michael Nygard presenting his ideas. After that, I knew I had to get hold of the book straight away.

I'd say this book was just average to me, but there's a reason behind it, which results from already adopted ways of dealing with software taken from a company I currently work for. But let's start from the beginning.

I still believe the book contains lots of useful information, but they are rather generic, you won't find any real code examples, information about edge cases and so on. I was aware of that prior to buying this position, but I've got a feeling that many information are repeated over

This book is fantastic.

Let's be frank: I'm biased, because the author is a friend and colleague, and I know some of the stories he tells from personal experience (I'm even in one of them, anonymously).

Nygard writes very well, taking complex concepts and breaking them down into their components, and leaving the reader with essential takeaways of the patterns that create problems and the patterns that can prevent them. The term is never used in this book, but the concept of DevOps underlies the

I was pretty sure I'd like it when, early on, I came across the following quote:

"...sites are now expected to be available 24 by 7 by 365." Footnote: "That phrase has always bothered me. As an engineer, I expect it to either be '24 by 365' or '24 by 7 by 52.'"

This book has a lot of good information on building web applications that can withstand very high load. It is well-written, and he does a very good job of explaining the reasons why different approaches are particularly good or bad.

Awesome! Must read for anyone who is(or wants to be) exposed to designing and running largely distributed(enterprisey) systems. In fact I'd recommend it to any engineer.

The book has plenty of real life stories, as well as good suggestions on how problems could have been mitigated beforehand.

Some of my takeaways:

Belongs on the bookshelf of every developer who values good night's sleep. Easily one of the best and most valuable software engineering books I've read - and it's been a few.

Full of case studies and practical, sound advices, this book will help you understand how you can actually successfully run and operate your service in production. Book covers a lot of ground and at the same time is able to get deep down to the core of topics it discusses. It is up to date with modern technologies and deve

One of the most interesting books I read recently. Usually this kind of material is pretty boring to read, but Michael Nygard presented it in a smooth and sometimes even funny way. Content-wise, even a seasoned person with experience of running software systems in production will find something interesting.
