At this year’s SQL PASS summit , I had the opportunity to talk with customers about App Fabric Cache and in preparation for the event, I put a demo to show some of the characteristics of the available APIs. The following is an explanation on how...

Abstract (updated version) Technical and commercial forces are causing Enterprise Architects to evaluate moving established on-premises applications into the cloud – the Microsoft Windows Azure Platform. This blog post will demonstrate that there are...

The distinguished field is used to expose the value of a node of a message instance to BizTalk Server system. However, if there is a record that has a parent node that has multiple instances, then that record won’t be able to be highlighted as distinguished...

Introduction One of the important reasons to move an application to the cloud is scalability (outside of other benefits that the cloud provides). When the application is deployed to the cloud, it is critical to maintain performance - the system needs...

Been tied up with PASS for the past (pun intended) couple of weeks, so it’s time to get a bit caught up on writing.  One of the key technical features of StreamInsight is the ability for one query to consume the output of another, enabling the system...

Introduction Some time ago, I was asked by a customer whether or not BizTalk WCF Adapters support the Duplex Message Exchange Pattern. The latter is characterized by the ability of both the service and the client to send messages to each other independently...

Recently, a particular deployment with cache servers on domain1 and cache clients (app servers or web servers) running on domain2 lead to some debugging challenges when the cache clients are unable to communicate with the servers. Whether it is your DEV...

This is a question that has come up in a few customer engagements, and on several forum posts – how do I find the top category in a stream for a given group?  Several examples of this pattern of question are: Given a stream of Product View events...

Another little LINQ error you might encounter from time to time. Ran into this yesterday while building out some queries, and figured it was worth a quick post. Starting with a basic stream, I needed to group by a set of fields in the stream and calculate...

"Yet another post on AppFabric Monitoring" I hear you saying. Indeed, and one that you may want to read, especially if you're using AppFabric mostly for management and monitoring of code-based WCF services. If you had already looked at, or even better...

  In the middle tier AppFabric (AF) Caching can be setup in High Availability (HA) mode which is the feature that improves resiliency in the case a cache server goes down and for the backed, when using SQL for your configuration database, the simplest...
