Key Takeaways             Three primary aspects of evolutionary architecture: fitness functions, incremental change and appropriate coupling Design for change on multiple dimensions (technical, data, security and operational) Combine DevOps (Continuous Delivery) practices with fitness functions to verify the architecture       Migrate to another architecture for good reasons (for example better team structure and operational isolation), not because “it’s the current trend” Building Evolutionary Architectures is a promising title for a book. I was also triggered and wanted to read the book. This is a review of the book with my own humble opinion. First a short description of the chapters is given. Chapter 1 - Software Architecture A definition of evolutionary architecture is described, which states that it supports guided, incremental...

Today I received a request to review a new book on SOA:   Service Oriented Architecture: An integration blueprint I feel honoured of course and in a few weeks I will receive a hard copy of the book. Looking forward to it and I will keep you up-to-date about my review ! Regards, Roger

I got this book on the second SOA Symposium in Rotterdam from one of the authors (Manas Deb) who happen to give a presentation there on SOA, BPM and EDA. He signed the book, so I have a unique piece :) This book gives you a prefect head start with the Oracle SOA Suite 11g. It explains the concepts of SCA, Database-, JMS- and File Adapter, BPEL, Human Tasks, Business Rules, OSB, Unit test of composite SCA applications, Security, Exception Handling, BAM, Event Delivery Network, SDO and B2B. All these concepts are explained with small tutorial examples. If you want to have in depth knowledge of the SOA Suite, this is not the correct book.

I bought this book to get a global overview of the possibilities of SCA, because it is also implemented within the Oracle SOA Suite 11g. It is the first book on the fairly new SCA standard. If you want to get a global overview the first chapter will already do. The next chapters go deeper into the concepts with Java as the example programming language. Chapter 1 - Introducing SCA The book starts with a global introduction of SCA and its place w.r.t. SOA, J2EE, .NET, Spring and distributed computing. SCA focuses on being able to describe assemblies of components which have been written in a variety programming models and protocols . It does not cover presentation and persistency. Within this chapter the main terms are explained: Service , Component , Composite and Domain . Why another standard? Because there are still some issues with J2EE and .NET, namely complexity and reusability. You have to understand a lot of different technologies like JAX-WS, JMS, EJB, ASP.NET, .NET M...
