Item description for SOA Approach to Integration by B. Juric Matjaz...

This book shows how to define SOA integration architecture, what technologies to use, and how to best integrate existing applications with modern e-business solutions. The book also shows how to develop web services, how to process and manage XML documents from JEE and .NET platforms, and how to use ESBs and BPEL executable business processes within SOA architecture.

Integration of applications within a business and between different businesses is becoming more and more important. The needs for up-to-date information that is accessible from almost everywhere and developing e-business solutions -- particularly business to business -- require that developers find solutions for integrating diverse, heterogeneous applications, developed in different architectures and programming languages and on different platforms. They have to do this quickly and cost effectively, but still preserve the architecture and deliver robust solutions that are maintainable over time.

Integration is a difficult task. This book focuses on the SOA approach to integration of existing (legacy) applications and newly developed solutions, using modern technologies, particularly web services, XML, ESB, and BPEL. The book shows how to define SOA for integration, what integration patterns to use, which technologies to use, and how to best integrate existing applications with modern e-business solutions. It also shows how to develop web services and BPEL processes, and how to process and manage XML documents from the JEE and .NET platforms. Finally, it also explains how to integrate both platforms using web services and ESBs.

  • Service-Oriented Architectures and SOA approach to integration
  • SOA architectural design and domain-specific models
  • Common Integration Patterns and how they can be best solved using Web services, BPEL and Enterprise Service Bus (ESB)
  • Concepts behind SOA standards, security, transactions, and how to efficiently work with XML

This book is for architects and senior developers who are responsible for setting up SOA for integration for applications within the enterprise (intra-enterprise integration) and applications across enterprises (inter-enterprise integration or B2B).

Reviews - What do customers think about SOA Approach to Integration?

Good book on SOA and WebServices Programming  Jul 24, 2008
The authors having had real world experience on how to develop SOA, have presented this book focusing more on practicality. They have worked in different websites and online companies where they specialized either in the development of SOA or working on a specific web language that also leads to the architecture.

Because of their experience with Packt Publishing and their real world experience for SOA, Packt has chosen them to write this book about SOA Integration.

Clearly this book requires deep familiarization of the components discussed in SOA. XML and Web Services are extensively discussed so that developers will understand why the mark-up language (XML) and approach (Web Services) is perfect for integration which eventually leads to SOA. For those who are beginning in SOA, this book provides explanation in great detail in the basic concepts of SOA - from the challenges until specific terms that will greatly influence in building an application using the architecture.

What is even interesting is that it provides an insight to an alternate to JavaEE and the .Net framework. If you have a vague idea of what COBRA is, then this book will enlighten you further why this application web language could help you in building an application.

Some parts of the book are great for beginners while other parts of book are intended for advanced users. If you are looking for specific instructions on how to integrate XML to SOA, then this book will help you. For beginners or for those who just wants an in depth information of SOA, then this book will also be of great assistance.

Ultimately, this is a great addition to your library as it provides the basics while introducing you to the advanced concepts and principles behind SOA.
Good material on SOA, ESB, and BPEL: Review by Tod McKenna of  Apr 19, 2008
This book was overall pretty good. The author details Service and Process Oriented Architectures (SOA/POA) and presents a solid approach to SOA integration. The highlight of the book is Chapter 6 (which, by the way, could have titled better!) that really dives into ESB (Enterprise Service Bus).

I gave it 4 stars mainly because it kept me interested throughout AND Chapter 6 was well worth the wait. Also, the author was direct and decisive in what he was saying. I never felt while reading that he was talking over my head or down to me from some higher plateau.

Some criticisms which kept it from a perfect 5 include:

(a) Too many repeated themes. I felt at times that I was reading the same sentence and paragraph over and over. Not a major thing, but I think I read that XML is a "standard" for organizations to exchange business data more than twice!
(b) The author throws around many acronyms, some of which without expanding. At one point, he used "PO" to refer to "Purchase Order" and I really had to stop reading and thing about what on earth a PO was (duh!). There are several examples of this throughout the text making it a bit difficult to read.
(c) Related to (b), I would have liked to read more background on some of the technologies discussed. Examples include the Java technologies that the author refers to throughout. I'm not a Java developer, so I felt a little behind in some of the discussion.
(d) I think the author spent too much time on his low-level XML discussion. I realize that XML is integral to SOA but for a book designed for "architects" and "senior developers", as the back cover suggests, it seemed too deep for "architects" to care about and too shallow for "senior developers". It might have been better to present an XML primer and leave it at that.
(e) By reading this book, I DO NOT feel ready to build an SOA, nor do I feel qualified to jump into a team implementing SOA.

Chapter 1 was a sufficient setup for the chapters to come. It would have been good to build a better case for SOA, though. If I was on the fence about SOA, I don't think this book would have convinced me that my organization needed to go down this path. This chapter does however provide a lot good background and helps draw the line between different integration strategies.

Chapter 2 introduces the ESB -- which for me is the most interesting aspect of the SOA approach. There is also a good discussion about processes and orchestration, which was enlightening (coming from me, who has no real world SOA experience).

Chapter 3 was the lowlight. I found myself skipping ahead when the author started discussion XML schemas, namespaces, declarations, and the like. I know this stuff already and was wondering how an "architect" or "senior developer" (I've been called both) would treat this chapter. I concluded that they would do essentially what I did: skim it. It is too light to be a reference and too heavy to be of any practical value.

Chapter 4 was better than the previous chapter. I like history (IT Evolution, and WS Specifications) and discussions on Patterns (the author discusses integration patters, business patterns, composites, application patterns, and runtime patters). He does however loose me a bit on writing WSDL and the simple web service example. I've written several web services and understand the concepts so I found myself skipping ahead a bit.

Jaded by some of what I read in Chapters 3 and 4, Chapter 5 got me back in the mood. BPEL. Finally. The book had been talking about BPEL (Business Process Execution Language) on-and-off and now this chapter gave me a heavy dose. Good job.

Chapter 6 was my favorite chapter by far. ESB is an area of interest for me, and to have it explained and examined in the context of SOA was eye opening. In fact, it's one of the reasons I wanted to read this book in the first place.

All-in-all, I learned a lot from this material. I took a few notes, which will lead to further research on my part. This book presents a good overview of some of the complexities and key points in building an SOA infrastructure/environment. Get it if that is what you're looking for!

Good Overview with details as well  Feb 20, 2008
It is a good overview of SOA concepts combined with Integration viewpoint. Integration is handled within SOA. SOA is about integration. Process Oriented Architecture was a term that was introduced. POA is about using BPEL to manage business processes with existing services.

All in all, a good review of SOA issues including ESB, WS specifications, XML considerations. Good explanation of concepts plus some of the nitty gritty details as well. Good all round.

There are 6 chapters:

1.Integration Architecture, Principles and Patterns

Review of different integration technlologies and types of integration
overview of integration challenges, process is important
SOA and its associated technolgies is a valid approach to integration

2.Service and Process Oriented Architectures

POA is centered on the processes that "use" the services while SOA is about"providing" the services.
POA is the approach from the business side of things. It is about business process and main standards include BPEL, WSCI, etc.

3.Best Practices for Using XML for Integration

Review of XML with tops and issues to watch out for.

4.SOA and Web Services Approach for Integration

SOA is not web services but web services are the specification/technology of choice in the arena.
WS applies to both EAI and B2B as well as SOA.
Included some on the specification process.

5.BPEL and Process-Oriented Approach

Familiarization with BPEL and POA together.
With a sample application of BPEL towards a Billing Process

6.Service and Process Oriented Approach to Integration using Web Services

Putting it all together with the Enterprise Service Bus(ESB).
Discussion of the ESB and what it offers for Integration and SOA.
I enjoyed this book  Feb 8, 2008
This book does a good job of covering and tying together a broad range of material with respect to the title topic. It provides a varying degree of detail in different areas, for example a light treatment of SOA in chapter 2 yet a more in-depth look at XML in chapter 3. The intended audience is noted as architects and developers so this variance may make sense but it seems inconsistent at times. Overall I thought this was a good book for anyone interested in the topic and a good reference for those who have been tasked with an integration project.

1.) Integration Architecture, Principals, and Patterns - covers a wide variety of concepts including types of integration including data, application, process and presentation. It also speaks to layers of integration such as communications, brokering, routing, transformation and others. The authors touch on various technologies in the integration arena, for example, database access, message oriented middleware, remote procedure calls, transaction monitors and more. The chapter finishes up with a quick overview of the integration process, various practices activities and patterns.

2.) Service and Process-Oriented Architectures for Integration - talks a great deal about the concepts and standards that make up Service and Process Oriented Architecture. It is not an in-depth tutorial on either subject but is a good reference for the standards associated with them and why they are well suited for integration.

3.) Best Practices for Using XML for Integration - is closer to a tutorial on XML than a description of the architectural rationale and implications of it with respect to SOA. Since part of the target audience is developers the level of detail in this chapter is not un-warranted. This chapter includes a comparison of JAXP API's and shows a number of XML schema and XSL stylesheet examples. It also speaks in reasonable detail to validation, security, encryption and performance considerations with respect to XML.

4.) SOA and Web Services Approach for Integration - steps more deeply into the area of web services and again much of it is directed to developers as opposed to architects. It contains a good overview of various patterns and contains some guidelines on their usage. The chapter contains a light review of web services for B2B and EAI and then a more detailed description and examples of interoperable web services, WSDL and WS-I.

5.) BPEL and the Process-Oriented Approach for Integration - speaks in more detail about BPEL and what the authors refer to as "the process-oriented approach to SOA-based integration.". This chapter addresses the usual suspects of choreography, orchestration and complexity in a clear fashion. It then goes into more depth on writing BPEL processes and works through a fairly complete example.

6.) Service and Process-Oriented Approach to Integration Using Web Services - gets to the heart of the notion of using SOA for integration by delving into the Enterprise Service Bus (ESB). This chapter covers the ESB at the appropriate level of abstraction for an architect and touches on key areas such as mediation, transformations, communications, transactions and security.

I enjoyed the book and felt it delivered on the topic of SOA Approach to Integration. Trying to target both architects and developers is a difficult task but readers from either area will find something useful in this book. It is not the definitive work on SOA and Integration but it does a good job of tying together a broad range of material and will be a welcome addition to anyone's technical library.
Basic overview that rehashes other materials  Jan 3, 2008
This is a mediocre book that provides basic information but little of the insight that creates knowledge. As the title implies, it doesn't teach SOA in general, just how to approach application integration using SOA. Even in that, its treatment of the topic is reasonably accurate but superficial.

The book's six chapters are a reasonably logical overview of basic SOA and integration topics that finally culminates in the discussion promised by the book title.

Chapter 1 explains why integration is important, a topic that goes back at least as far as David Linthicum's Enterprise Application Integration (Addison-Wesley Information Technology Series). It lists numerous aspects of application integration without giving particular insight into any of them nor comparing them--a theme with this book's material.

Chapter 2 explains what SOA is. Its treatment of SOA is very superficial, little more than a technology that can be used for integration, and so should not be read as a thorough overview of why SOA is important. To understand SOA's importance, see Service Oriented Architecture For Dummies (For Dummies (Computer/Tech)) (yes, a Dummies book, but helpful!). One of the main advantages of SOA is its improved ability (as compared to other architectural approaches) to align IT and business, that is to make a company's applications and its business work in a more similar fashion. For a good discussion of business/IT alignment, see The New Language of Business: SOA & Web 2.0.

Chapter 3 is an XML primer, which seems pretty low-level for an architectural book. It explains a lot through XML and schema code examples, and even gets into an explaining and comparing SAX, DOM, and StAX. This chapter would better serve the book if it had focused more on the architectural decisions for XML and the implications of those decisions.

Chapter 4 is a primer on Web services and again gets fairly low-level for an architectural book. It explains the need to integrate heterogeneous systems, often connected via Internet technologies, and eventually discusses WSDL (but not SOAP!), WS-I profiles, and interoperability between Java EE and .NET. In between, however, it discusses patterns for integration by lifting material wholesale from IBM's Patterns for e-business and subsequent Redbooks on the topic. The diagrams in this book are straight out of the IBM materials, to the point of (what seems like) copyright violation.

Chapter 5 focuses on BPEL and what the book calls "process-oriented architecture." This is an interesting turn, since business process is not so much integration using services as it is a useful abstraction for implementing services--especially long-running ones--using other services. So whether this is integration of business functionality or composability of business functionality is debatable. In any event, the book then dives deep on BPEL features and code examples. Other books on BPEL may be more helpful.

Chapter 6, the last chapter, finally gets to the book's topic, application integration using SOA, POA, and Web services. Here, the book finally starts to explore the enterprise service bus (ESB), although for some reason considers the ESB to be not just a means for connecting to service providers, but a hosting environment for service providers as well! A lot of the material here is a rehash of Enterprise Integration Patterns: Designing, Building, and Deploying Messaging Solutions (The Addison-Wesley Signature Series); although this book's authors don't seem to have read that book, they discuss a lot of the same topics in terms of implementing Web services. Curiously, one section covers Java Business Integration (JBI), which only applies to Java, and yet the book never discusses a similar and more interoperable programming model, service component architecture (SCA).

In conclusion, what material this book covers, other books cover better. The advantage of this book is providing brief overviews of the material and tying it together better than separate books can. Yet this book's coverage of these topics is too low-level for architects, too brief for developers, and too superficial to teach the topics to readers who don't already know them. Other books on SOA and on application integration are better.

Disclaimer/qualifications: I am a coauthor of Enterprise Integration Patterns and work for IBM. The publisher (Packt) sent me a copy of this book and asked me to review it.
