Communication is everywhere. The Windows Communication Foundation (WCF) can be used to design and develop service-oriented distributed solutions. This presentation shows the basics of WCF and how to solve common problems in distributed systems. Christian Weyer provides a practical approach to realizing distributed solutions with WCF - beyond the hype and 'Hello World'.
As the problem domain of your Rails applications expands, you may need to run computationally intensive or long running background tasks. How can you run these long background tasks without your web server timing out? And how do you display the progress to your users?
SOA Expert Steve Jones from CapGemini provides a hands on look at SOA Antipatterns and a list of ways your SOA project can go wrong. This list includes signs that these problems are cropping up as well as what to do when you see them happening.
Jim Webber re-ignited some interesting discussions about the need (or not) for Cohesive Services within SOA. What started as a fairly innocuous post has certainly generated a lot of debate.

In a new InfoQ minibook, InfoQ SOA Editor and SOA Enterprise Architect Jean-Jacques Dubray describes the state of the art and emerging new approaches in building "Composite Software", solutions created by assembling existing services. The book is available as an InfoQ Minibook, i.e. free of charge in PDF format for InfoQ users. A printed version is available too.
As we transition from component architectures to service oriented architectures, the balance between natural, efficient asset reuse and independent, decoupled systems is a real battleground. Neal Ford recently posted some thoughts about high coupling and it's unintended consequences, and we revisit a great InfoQ interview with Jim Webber about tight coupling as it applies to service architectures.
In this article Stefan Tilkov, innoQ SOA consultant and InfoQ SOA Community editor, introduces a potential set of roles for successful SOA Governance. He describes the individual roles as well as the tasks assigned to each independent of any tool, vendor, or technology.
Nick Malik writes about "The Value of Intermediation in SOA", which started an interesting discussion. In his first blog post on the subject he asked the question: "Is it Service Oriented if the message cannot be intermediated?".
Composite Software offers a new level of granularity when compared to SaaS (Software as a Service). Composite Software is about enabling "right-sourcing", i.e. move (or keep) arbitrary small or large elements of functionality wherever it is the most cost effective to operate them, not just entire systems. Economically, "right-sourcing" is far more efficient than "outsourcing" and SaaS. The goal of this book is start by understanding today’s software construction processes and technologies and explore why and how it should be evolved to support core composition mechanisms.
