Welcome to the first edition of the Microsoft® BizTalk® Server Performance Optimizations Guide. We created this guide to provide in depth information for optimizing the performance of a BizTalk Server solution. Full end-to-end performance testing is frequently overlooked during enterprise application deployment. Knowing that Microsoft has built a scalable messaging infrastructure, many organizations that use BizTalk Server spend little or no time conducting performance testing of their own applications. BizTalk Server applications consist of many parts, which may include custom-built components as well as those provided by Microsoft. It is impossible for Microsoft to performance test every possible combination of these components. Therefore, fully and properly conducting a performance test of your application is a critical step of any deployment. The purpose of this guide is to consolidate and provide prescriptive guidance on the best practices and techniques that should be followed to optimize BizTalk Server performance.

From CodePlex:

BizUnit Designer is a GUI that allows rapid creation of BizUnit test cases which can be used for unit testing or system testing distributed applications. The easy to use drag and drop user interface has minimal learning curve which will get you up and running with test cases in a matter of minutes.

I’ve used BizUnit on a couple of projects (even non-BizTalk projects) and I think it’s very useful. The only thing bothering me was that I always had to edit the XML files directly (although not difficult). This designer somewhat helps you with this. Unfortunately are all the test steps very different from each-other that building a generic designer can only help a little. The UI could use some tweaks to make it easier to use. Anyway I think it’s a great initiative, although not perfect.

Somebody at the product team has really started a rush to push out these nice looking posters. Here is a rather new one:

in case you haven’t seen this yet, Microsoft has a rather interesting marketing campaign around Windows Home Server. One of the parts of the campaign is a book about Home Server which looks like it’s written for kids. The book explains what the magic ‘Server’ in the house is all about.

Microsoft went so far with this campaign that it actually looks like you can buy the book from Amazon! Absolutely hilarious!

If you would like to know more about that weird ‘Server’ that suddenly appeared in your house and what it does, you should definitely read the book!

From the almighty Scott Hanselman:

Released today are four new screencasts about the ASP.NET 3.5 Extensions by various members of the ASP.NET team. Every video is available in numerous formats, and note that this also includes re-encoded versions of my Intro to MVC Screencast in a pile of formats including an iPod/iTouch compatible format, as well as ones for the Zune and PSP and a utterly unwatchable 40 meg 3GP one for 3G Phones.

In this video, James Conard talks with John Shewchuk and Dennis Pilarinos about BizTalk Services.

In the simplest definition, BizTalk Services simplifies application connectivity by extending WCF and providing a set of hosted services. John and Dennis quickly explain BizTalk Services by discussing the challenges with building applications today. Dennis also shows four demos of BizTalk Services and then drops into Visual Studio along the way to show the programming model.

Check out the video here.

Just released (oh well, a couple of months ago), the long awaited BizTalk Server 2006 extensions for Windows Workflow Foundation SDK. Use WF modeling and host workflows in BizTalk Server. Note the BTS messaging activities in the image.

The new BizTalk Server edition will most likely sport the Workflow Designer instead of the plain old Orchestration Designer. This probably results into something that looks a lot like what you get with the extentions. With the extentions you won’t have to choose between either product at the start of a project, but you could use both instead.

Note that this release is not supported by Microsoft customer services and should be treated as an SDK sample. If you still want to use this on a project or just want to play with it, you can download it here.

Microsoft LoadGen 2007 generates message transmission loads to run performance and stress tests for your Microsoft BizTalk Server applications, and provides performance counters to monitor the performance of the infrastructure running BizTalk Server.

This tool is intended for developers and IT professionals to simulate load on a BizTalk Server. Using this tool, you can simulate load to instrument performance and stress against a BizTalk deployment. In addition, this tool may also be extended by developers to simulate load for custom transports. This tool should be used in a test environment only, and should not be used in a production environment. This tool is provided “as-is” and is not supported.
