Hosting StreamInsight applications using WCF
One of the fundamental differentiators of Microsoft's StreamInsight compared to other Complex Event Processing (CEP) technologies is its flexible deployment model. In that sense, a StreamInsight solution can be hosted within an application or as a server component. This duality contrasts with most of the popular CEP frameworks in the current market which are almost exclusively server based. Whether it's undoubtedly that the ability of embedding a CEP engine in your applications opens new possibilities for CEP scenarios such as Web analytics or mobile CEP it is also unquestionable that the majority of CEP scenarios still rely on a server-centric model. This blog post provides an initial overview to the server hosting capabilities of Microsoft's StreamInsight.

Speaking at Microsoft's Duth DevDays
Last week I had the pleasure of presenting two sessions at Microsoft's Dutch DevDays at Den Hague. On Tuesday I presented a sessions about how to implement real world RESTFul services patterns using WCF, WCF Data Services and ASP.NET MVC2. During that session I showed a total of 15 small demos that highlighted how to implement key aspects of RESTful solutions such as Security, LowREST clients, URI modeling, Validation, Error Handling, etc. As part of those demos I used the OAuth implementation created by my colleague Pablo Cibraro.

Announcing Tellago DevLabs on CodePlex
It's been a few weeks since my last blog post mainly due to the fact that it's been an extremely busy month for us at Tellago. We have been heads down working on several fun projects that we are expecting to share with the dev community in the next few weeks. In any case, today I am really happy to put an end to my blogging hiatus by announcing the availability of Tellago DevLabs on CodePlex. The main purpose of this workspace is to provide a vehicle to share some of the open source projects we have been working on. At Tellago, we are firm believers in open source as a mechanism to make software better and we've decided to maintain a separate CodePlex workspace to publish several open source projects lead by members of Tellago technical staff. We are also expecting that this workspace will improve the interaction between our tech team and the .NET developer community.

WCF Extensibility Guidance Chapter 2
The second chapter of our WCF Extensibility Guidance Pablo and I authored a few months ago is now available on MSDN. This chapter is one of my favorites given that it touches upon the most common extensibility points of WCF's client and dispatcher programming model. Specifically, this chapter covers the best practices and techniques to implement the following WCF extensibility components:

Lightweight SOA
A few months ago my colleague Don Demsak and I started collaborating on a paper about the principles of "Lightweight SOAs". Fundamentally, the paper intends to demystify some of the aspects around big SOA enterprise projects and propose some patterns that facilitate the implementation of these architecture using emerging architecture styles (REST, cloud computing, etc) and technologies in a very agile manner. Thanks to Diego Dagum and his team, the paper has been included in the latest issue of the Microsoft Architecture Journal.

Implementing a SAML sender-vouches scenario with WIF
Sender-vouches is one of the two subject confirmation methods included in the SAML security token profile specification. Essentially, the sender-vouches scenario enables an attesting entity to vouch for the identity of a subject to a relying party. The following figure illustrates this scenario:

Microsoft and Oracle showcase WS Interoperability at Gartner’s AADI summit
As you might have noticed, I haven't been actively blogging during the last month. The reason is that I have been hands on working on a very ambitious project to showcase Web Services interoperability between Microsoft and Oracle platforms. This experiment allowed us to explore the interoperability of WCF 4.0 and WIF RTM with the upcoming release of Oracle WebLogic within the context of a real world application. As a result, we were able to implement various complex WS interoperability scenarios encompassing diverse areas such as security, trust, federation, asynchronous reliable messaging, transactions, etc. We had the opportunity to experience firsthand the interop capabilities of both stacks as well as identify some of the areas that require improvement in order to achieve better levels of interoperability.
