Next Tuesday (November 10th) my colleague Uri Katsir will be presenting a session at the South Florida BizTalk Users Group about improving agility in large BizTalk environments using the ESB toolkit. If you are a BizTalk developer or operations architect working on complex BizTalk deployments you MUST attend Uri's session . In order to keep things in perspective, Uri has prepared a series of interesting demos that illustrate the techniques used to improve the development and management experience...( read more ) Read More...

For some reason the family of design patterns that exist around the Model View Controller pattern seem to be an elusive band of characters. The first time I encountered Model View Controller I studied the text hard trying to understand how the Strategy , Observer and Composite patterns worked together to accomplish some goal that – try as I might - remained fuzzy. Somehow I have a sense that I am not alone. Model View Controller (MVC) is the parent pattern to a number of contemporary patterns that seem to find a natural home in Microsoft development. Variations of MVC have appeared over the years in an attempt to work within the construct of modern event-driven programming models. One of most distinguishing differences among MVC and some of...

My friend and colleague Uri Katzir just joined the blogosphere. Uri is a BizTalk wizard who is currently working on one of the biggest BizTalk implementations in the world. We are extremely proud to have him as part of our technical staff at Tellago . Uri has already posted a couple of interesting write-ups about ESB itineraries troubleshooting and deployment techniques....( read more ) Read More...

As the WCF team already announced, the first chapter of the WCF Extensibility Guidance is now available on MSDN . This paper is the result of an effort I started a few months ago with my colleague and friend Pablo Cibraro . Our goal was to provide a detailed guidance of the major extensibility points of the WCF runtime. In that sense, we decided to cover major areas of the WCF extensibility programming model such as channels, client-dispatcher, security, hosting, metadata, RESTful service and even...( read more ) Read More...

In a previous post we explained the programming model of Microsoft's StreamInsight adapter framework. The fundamental capability of this framework is to streamline the flow of events in and out of the StreamInsight hosting application. One of the main advantages of this model is that enables developers to create their own adapters that can be leveraged on StreamInsight-based solutions. On this post we will explore the details of implementing an RSS/Atom adapter using StreamInsight's adapter framework...( read more ) Read More...

Adapters are a fundamental component of Complex Event Processing (CEP) applications. In a nutshell, adapters provide the interfaces that abstracts how events are produced or consumed by the CEP infrastructure. Most CEP frameworks leverage the concept of an adapter as the fundamental mechanism for interacting with heterogeneous systems. Following the same principles, Microsoft's StreamInsight uses adapters to model the flow of events in or out of the CEP host. Furthermore, StreamInsight enables a...( read more ) Read More...

One of the fundamental patterns of Complex Event Processing (CEP) applications is the ability of process events from various input sources and distribute to multiple output sources. These operations require high degrees of coordination what makes it particularly difficult to implement in real world scenarios. Why is that? Well, for starters, continuously querying data from multiple sources entails implementing certain degrees of parallelisms on the CEP application. As we all know, parallel processing...( read more ) Read More...

Here’s another email from the internal mailing list of Injazat .NET Ninjas (Ninjazat, AKA  as we call ourselves), that I’m sharing with blog readers as well. Just a place holder, until I move one of my 18 (just discovered the number now – terrifying!) drafts in my Windows Live Writer into a published post, or delete them all! Subject: [Learning] Some very interesting videos Some videos from NDC 2009 event (Norwegian Developers Conference 2009) - about software design and related issues: · NDC Video – Robert Martin – S.O.L.I.D Principles of OO class design · NDC Video – Robert Martin – Craftsmanship and Ethics · NDC Video – Robert Martin – Component Principles · NDC Video – Robert Martin – Clean Code III – Functions · NDC Video – Michael...

I will be speaking tomorrow at the South Florida Architecture User Group (ArcSig) . The session is titled From SOA to WOA: Introducing Web Oriented Architectures and touches upon the fundamental principles and architecture techniques that can help developers to implement distributed systems that leverage the principles of REST. If you are in the South FL area and you are interested on SOA, REST, WCF, etc…please attend to my session. I promise to keep things interesting ;)...( read more ) Read More...
