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.

Thomas Bitman of Gartner wrote a blog post last year about why OpenStack projects fail. In that article, he outlined three particular metrics which together cause 60% of OpenStack projects to fall short of expectations: Wrong people (31% of failures): a successful cloud needs commitment both from the operations team as well as from "anchor" tenants. Wrong processes (19% of failures): a successful cloud automates across silos in the software development lifecycle, not just within silos.

Let's just nip the conflation of these terms in the bud, shall we?

"MIcro" is big these days. Both microservices and microsegmentation are having and will continue to have an impact on data center architecture, but not necessarily for the same reasons. There's a growing trend in which folks - particularly those with a network background - conflate the two and use them to mean the same thing.

They are not.

One is about the application. The other, the network. T...

Sharding has become a popular means of achieving scalability in application architectures in which read/write data separation is not only possible, but desirable to achieve new heights of concurrency. The premise is that by splitting up read and write duties, it is possible to get better overall performance at the cost of a slight delay in consistency. That is, it takes a bit of time to replicate changes initiated by a "write" to the read-only master database. It's eventually consistent, and it'...
