Book Review: SOA with REST

Principles, Patterns & Constraints for Building Enterprise Solutions with REST

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.

The Internet of Things. Cloud. Big Data. Real-Time Analytics. To those who do not quite understand what these phrases mean (and let’s be honest, that’s likely to be a large portion of the world), words like “IoT” and “Big Data” are just buzzwords. The truth is, the Internet of Things encompasses much more than jargon and predictions of connected devices. According to Parker Trewin, Senior Director of Content and Communications of Aria Systems, “IoT is big news because it ups the ante: Reach out ...
At DevOps Summit NY there’s been a whole lot of talk about not just DevOps, but containers, IoT, and microservices. Sessions focused not just on the cultural shift needed to grow at scale with a DevOps approach, but also made sure to include the network ”plumbing” needed to ensure success as applications decompose into the microservice architectures enabling rapid growth and support for the Internet of (Every)Things.
Auto-scaling environments, micro-service architectures and globally-distributed teams are just three common examples of why organizations today need automation and interoperability more than ever. But is interoperability something we simply start doing, or does it require a reexamination of our processes? And can we really improve our processes without first making interoperability a requirement for how we choose our tools?

JavaScript is primarily a client-based dynamic scripting language most commonly used within web browsers as client-side scripts to interact with the user, browser, and communicate asynchronously to servers. If you have been part of any web-based development, odds are you have worked with JavaScript in one form or another. In this article, I'll focus on the aspects of JavaScript that are relevant within the Node.js environment.
One of the ways to increase scalability of services – and applications – is to go “stateless.” The reasons for this are many, but in general by eliminating the mapping between a single client and a single app or service instance you eliminate the need for resources to manage state in the app (overhead) and improve the distributability (I can make up words if I want) of requests across a pool of instances. The latter occurs because sessions don’t need to hang out and consume resources that could ...

Software is eating the world. The more it eats, the bigger the mountain of data and wealth of valuable insights to digest and act on. Forward facing customer-centric IT organizations, leaders and professionals are looking to answer questions like how much revenue was lost today from platinum users not converting because they experienced poor mobile app performance. This requires a single, real-time pane of glass for end-to-end analytics covering business, customer, and IT operational data.
Approved this February by the Internet Engineering Task Force (IETF), HTTP/2 is the first major update to HTTP since 1999, when HTTP/1.1 was standardized. Designed with performance in mind, one of the biggest goals of HTTP/2 implementation is to decrease latency while maintaining a high-level compatibility with HTTP/1.1. Though not all testing activities will be impacted by the new protocol, it's important for testers to be aware of any changes moving forward.

You often hear the two titles of "DevOps" and "Immutable Infrastructure" used independently. In his session at DevOps Summit, John Willis, Technical Evangelist for Docker, covered the union between the two topics and why this is important. He provided an overview of Immutable Infrastructure then showed how an Immutable Continuous Delivery pipeline can be applied as a best practice for "DevOps." He ended the session with some interesting case study examples.
