|This book does what it patterns book should do. It defines a language for enterprises to use to develop SOA solutions using REST.
The book starts off with two chapters. The first chapter is an introduction and shows how the book is laid out. Chapter 2 introduces two case studies that are used throughout the book to provide examples of how the patterns can be applied to real-world situations.
After the first two chapters of the book is broken down into six parts. I have listed the parts below with their associated chapters.
Chapter 1: Introduction
Chapter 2: Case Study Background
Part I: Fundamentals Chapter 3: Introduction to Services
Chapter 4: SOA Terminology and Concepts
Chapter 5: REST Design Constraints and Goals
Part II: RESTful Service-Orientation
Chapter 6: Service Contracts with REST
Chapter 7: Service-Orientation and REST
Part III: Service-Oriented Analysis and Design with REST
Chapter 8: Mainstream SOA Methodology
Chapter 9: Analysis and Service Modeling with REST
Chapter 10: Service-Oriented Design with REST
Part IV: Service Composition with REST
Chapter 11: Fundamental Service Composition with REST
Chapter 12: Advanced Service Composition with REST
Chapter 13: Service Composition with REST Case Study
Part V: Supplemental
Chapter 14: Design Patterns for SOA with REST
Chapter 15: Service Versioning with REST
Chapter 16: Uniform Contract Profiles
Part VI: Appendices
Appendix A: Case Study Conclusion
Appendix B: Industry Standards Supporting the Web
Appendix C: REST Constraints Reference
Appendix D: Service-Orientation Principles Reference
Appendix E: SOA Design Patterns Reference
Appendix F: State Concepts and Types
Appendix G: The Annotated SOA Manifesto
Appendix H: Additional Resources
In Chapter 14, Design Patterns for SOA with REST, the author introduces seven new patterns. They include Reusable Contract, Lightweight Endpoint, Entity Linking, Endpoint Redirection, Content Negotiation, Idempotent Capability, and Uniform Contract. All of the new patterns are nicely tied to currently existing patterns that appear in the author's other books.
One of my favorite parts of the book is that it shows the relationship between SOA and REST. REST architecture provides a medium by which service oriented architecture can be implemented. This book does an excellent job of clearly defining the relationship.
Another thing I really like the book is the low-level granularity that it goes into when describing the pattern languages Used for implementing SOA using REST.
The author does a great job of showing how the goals of the rest architectural style meet certain quality attributes. Quality attributes he covers include performance, scalability, simplicity, modifiability, visibility, portability, and reliability.
I would have liked to see more coverage of security. Although mentioned several times, it was not really covered. It would have been nice to see them cover hash-based message authentication code as one of the patterns used in REST architecture. Maybe it isn't used as widely as it appears to be used.
The author does have a Visio stencil available for download that includes all of the modeling symbols used in his SOA books, but does not appear to have updated with the REST symbols yet.
I believe this book did a nice job of filling in an existing gap in the SOA pattern books.
All in all if you are considering learning REST or SOA you should make this book part of your library. I felt the author did a good job of introducing both SOA and REST in the beginning of the book, so this book is perfect for the beginner. I also felt the author went deep enough into detail to make this book valuable to the more experienced developer.
Most importantly I feel the author nailed the goal of a pattern book and accomplished creating a reference for the language of SOA with REST for development teams to have a common vocabulary to communicate with.

It's 2:15pm on a Friday, and I'm sitting in the keynote hall at PyCon 2013 fidgeting through a succession of lightning talks that have very little relevance to my life. Topics like "Python code coverage techniques" (ho-hum) and "Controlling Christmas lights with Python” (yawn - I wonder if there's anything new on Hacker News)...when Solomon Hykes takes the stage, unveils Docker, and the world shifts. If you haven't seen it yet, you should watch the video of Solomon's Pycon The Future of Linux C...

This month I want to revisit supporting infrastructure and datacenter environments. I have touched (some would say rant) upon this topic since my post in April 2014 called "Take a Holistic View of Support". My thoughts and views on this topic have not changed at all: it's critical for any organization to have a holistic, comprehensive strategy and view of how they support their IT infrastructure and datacenter environments. In fact, I believe it's even more critical today then it was a year ago ...

Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...

Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...

Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Microservices, for the uninitiated, are essentially the decomposition of applications into multiple services. This decomposition is often based on functional lines, with related functions being grouped together into a service. While this may sound a like SOA, it really isn't, especially given that SOA was an object-centered methodology that focused on creating services around "nouns" like customer and product. Microservices, while certainly capable of being noun-based, are just as likely to be v...

You hear the terms “subscription economy” and “subscription commerce” all the time. And with good reason. Subscription-based monetization is transforming business as we know it. But what about usage? Where’s the “consumption economy”? Turns out, it’s all around us. When most people think of usage-based billing, the example that probably comes to mind first is metered public utilities — water, gas and electric. Phone services, especially mobile, might come next. Then maybe taxis. And that’s ab...

As a group of concepts, DevOps has converged on several prominent themes including continuous software delivery, automation, and configuration management (CM). These integral pieces often form the pillars of an organization’s DevOps efforts, even as other bigger pieces like overarching best practices and guidelines are still being tried and tested. Being that DevOps is a relatively new paradigm - movement - methodology - [insert your own label here], standards around it have yet to be codified a...

An explosive combination of technology trends will be where ‘microservices’ and the IoT Internet of Things intersect, a concept we can describe by comparing it with a previous theme, the ‘X Internet.' The idea of using small self-contained application components has been popular since XML Web services began and a distributed computing future of smart fridges and kettles was imagined long back in the early Internet years.
