Monolith to Microservices

Evolutionary Patterns to Transform Your Monolith

De: Sam Newman

Narrado por: Mitchell Dorian

How do you detangle a monolithic system and migrate it to a microservice architecture? How do you do it while maintaining business-as-usual? As a companion to Sam Newman’s extremely popular Building Microservices, this new book details a proven method for transitioning an existing monolithic system to a microservice architecture.

With many illustrative examples, insightful migration patterns, and a bevy of practical advice to transition your monolith enterprise into a microservice operation, this practical guide covers multiple scenarios and strategies for a successful migration, from initial planning all the way through application and database decomposition. You’ll learn several tried-and-tested patterns and techniques that you can use as you migrate your existing architecture.

• Ideal for organizations looking to transition to microservices, rather than rebuild
• Helps companies determine whether to migrate, when to migrate, and where to begin
• Addresses communication, integration, and the migration of legacy systems
• Discusses multiple migration patterns and where they apply
• Provides database migration examples, along with synchronization strategies
• Explores application decomposition, including several architectural refactoring patterns
• Delves into details of database decomposition, including the impact of breaking referential and transactional integrity, new failure modes, and more

Lots of great points

This book contains some amazing points. My only critique is that he under emphasizes the warnings such as too many undersized services, the coupling caused by orchestration, or describing how to determine micro-service boundaries.

Teach you how to think about choices

Read this book… even if you’re not going to do micro services. this book covers so much, impacts of centralizing versus decentralizing technology choices strategies for risk reduction of architecture scale, how corporate culture institutional technical maturity impact (and impacted by) the technology choices you make– I just finished my first listen through it won’t be my last.

Narrator is awesome

You know how awesome Sam is, so I focus on the narrator. He changes his tone so that we don't fall asleep and have a better understanding of the book. Moreover, similar to Benjamin Lange and Theodore O'Brien, Mitchell does the hard work of paraphrasing the the pictures and injecting it to the narration. Unfortunately other narrators, lazily read what is written: "as shown in figure 1-1" without having an empathy that the poor listener might not be able to see the book. A shoutout to Upfront Books for its amazing narrators: Mitchell Dorian, Benjamin Lange, and Theodore O'Brien :)

Clear Concise

I enjoyed the content as well as delivery.
The book gives a great insight into breaking out services as well as various approaches and methods pitfalls.

content was great

content was great.. awesome topics and covered end to end subject area.. delved into the details of each chapter as well..

Pretty good, but could be better

Overall, it’s a good book with useful information presented in an easy to understand manner.
Narrator is clear and performs well.

Although the book includes important guidelines and practices, I was expecting a more detailed approach with examples I can relate to.
As there wasn’t a deep dive into the way of breaking a database and library into microservices, I finished the book with a feeling I’d need to explore much more on topics mentioned in the book.

If Sam writes another book with a step by step migration of a real monolith to microservices that would make both this book and the value of both awesome.

Very informative and well done

I listened to the audio book while reading the paper copy. This helps keep my mind from wandering and I get more out of what I’m reading even though I speed up the audio. The only issue I had is that periodically the text differs from the audio because of references to graphs, etc. The book is an excellent reference and overview of converting to microservices. I particularly appreciate Appendix B, the pattern index in the hard copy.

good top level summery with references to details.

Good overview. admitting tha microserviced may not always be a good path to take. Defining what to valuate tovdefine future targets. Giving referenced to both real cases ad welss ss other places to deep dive into topics needing further details.

Not much new

I found this book to me more of a recap of Building Microservices 2nd Edition. Read that instead.
