Windows Azure Service Bus Scatter-Gather Implementation
One of the more challenging enterprise integration patterns that developers may wish to implement is the Scatter-Gather pattern. In this article I will show the basic implementation of a scatter-gather pattern using the topic-subscription model of the windows azure service bus. I’ll be using the implementation in demos, and also as a lab in my training courses, and the pattern will also be included in the next release of my free e-book the “Windows Azure Service Bus Developer Guide”. The Scatter-Gather ......

Windows Azure Service Bus Splitter and Aggregator
This article will cover basic implementations of the Splitter and Aggregator patterns using the Windows Azure Service Bus. The content will be included in the next release of the “Windows Azure Service Bus Developer Guide”, along with some other patterns I am working on. I’ve taken the pattern descriptions from the book “Enterprise Integration Patterns” by Gregor Hohpe. I bought a copy of the book in 2004, and recently dusted it off when I started to look at implementing the patterns on the Windows ......

Transactional Messaging in the Windows Azure Service Bus
Introduction I’m currently working on broadening the content in the Windows Azure Service Bus Developer Guide. One of the features I have been looking at over the past week is the support for transactional messaging. When using the direct programming model and the WCF interface some, but not all, messaging operations can participate in transactions. This allows developers to improve the reliability of messaging systems. There are some limitations in the transactional model, transactions can only ......

Windows Azure Service Bus Resequencer
Introduction I’ll be presenting a session at Sweden Windows Azure Group (SWAG) on Monday, as well as presenting on the Windows Azure Service Bus at various other events. I thought it would be fun to look at implementing some of the Enterprise Integration Patterns using the brokered messaging capabilities. I’ll use this article in the next release of Windows Azure Service Bus Developer Guide, and it will probably end up as a “challenge lab” for my Service Bus course. As a long-time BizTalk developer ......

Deadlettering in Azure AppFabric Service Bus Brokered Messaging
I’ve just published an article on deadlettering on “Deadlettering in Azure AppFabric Service Bus Brokered Messaging”. It looks at how deadlettering can be used to handle poison messages, and messages that do not meet business rules. The article will be included in the next release of “The Developer’s Guide to AppFabric”, a free e-book on Azure AppFabric development. The latest edition of the e-book is available for download here ......

Webcast – BAML – A DSL for BAM
I never really “got” the idea of the need to build a textual DSL when I was first introduced to MGrammar. The light really switched on when I looked into developing a DSL that would make it easier for developers to create BAM activities. The BAML language only took a couple of hours to develop. I had experimented with simple text based DSLs before, so this was my first “real” language. I have recorded a 20 minute webcast showing how the language works, and how it can be used. If you want to experiment ......

Sweden Windows Azure Group (SWAG) meeting on Thursday 27th October in Stockholm, "Extending to the Cloud",
I’ll be presenting a session on “Extending to the Cloud” at the Sweden Windows Azure User Group next week. Extending to the Cloud Extending to the cloud involves developing hybrid applications that leverage the capabilities of cloud based platforms. Many of the Windows Azure solutions developed today involve extending the capabilities of existing applications and infrastructure to leverage the capabilities of Azure. These hybrid applications allow developers to combine the best of both worlds. Existing ......

Two Great AppFabric Resources
If you want to get up to speed on Azure AppFabric brokered messaging there are a couple of resources you should check out. SB CTP Messaging User Guide This is a 30 page word document put together by the AppFabric dev team. It’s a great read to get an introduction to Queues, Topics and Subscriptions. If you are working in the AppFabric Labs environment using the May or June CTP the code will work fine. There have been significant changes in the API in the September 2011 release, so don’t expect any ......

Another AppFabric Walkthrough - Introducing Topics and Subscriptions
I’ve added a third walkthrough to the AppFabric Walkthrough series. “The following walkthrough will show how topics and subscriptions can be used to implement a simple publish-subscribe messaging channel. The next walkthrough will build on this sample and explore the use of filters on subscriptions.” Introducing Topics and Subscriptions The other two walkthroughs are here.

AppFabric Walkthrough: Creating a Simple Queue Management Tool
I’ve added a second AppFabric Walkthrough based on the Azure AppFabric Service Bus September 2011 release. The second one looks at using the NamespaceManager class to create, list, get and delete queues in an AppFabric service bus namespace using a simple C# console application. Feel free to expand on this scenario to create more sophisticated management consoles. As with the first walkthrough there have been a lot of changes in the classes used to interact with the service bus, so don’t expect this ......

AppFabric Walkthrough: Simple Brokered Messaging
I’ve published a basic walkthrough of using the new brokered messaging capabilities in the Azure AppFabric service bus September 2011 release. If you have not used queues in AppFabric before this will get you started with a basic application that you can build upon. If you have used queues in the May or June CTP releases then this walkthrough will be useful to highlight the changes in the management portal and service bus API. (Quite a lot has changed, for the better, but I have a lot of rework to ......

Windows Azure AppFabric SDK V1.5 September 2011 – Brokered Messaging is Live!
The Azure AppFabric Service Bus Brokered Messaging functionality has shipped to production, and is available in Azure data centers across the world. This means that we now have point-to-point queuing and publish-subscribe messaging available in the cloud in the form of Queues, Topics and Subscriptions. Be aware that there are substantial changes in the classes in the Microsoft.ServiceBus.Messaging namespace, which means I will have to re-record webcasts and repost blog posts.

Who Moved my Cloud?
Due to technical issues, (well, me not reading my hotmail account or any Azure blogs actually) I had a slight “outage” on CloudCasts. The USA-Northwest Azure data centres closed, taking my site with it. After a frantic couple of hours (midnight to 2 AM Swedish time) I’m back up and running in a shiny new data centre in USA-Southwest. The site is now running again at www.cloudcasts.net, but due to the change in the Azure app name, links to cloudtv.cloudapp.net are broken. At the moment I am seeing ......

Visual Studio 2010 Beta 2 Workflow Designer Webcast
As the public launch of Visual Studio 2010 Beta 2 is probably old news in the BlogSphere by now, I thought I’d try and get an early webcast out. I spent about an hour playing with the new Workflow Foundation (WF) designer, and have to say it’s looking pretty good. I didn’t think that much of it in the PDC bits or Beta 1, but both the Sequential and Flowchart workflow designers are now very nice to develop with. I’ve not has the chance to look at any complex problems or do any heavy lifting with them, ......

CloudCasts Update
I’ve spent a bit of time with CloudCasts (formally Cloud TV). I changed the name for a couple of reasons, primarily because the domain name cloudcasts.net was available. I’m still hosting in Azure, and the original links will work as long as its Azure hosted, but you should update the links to use www.cloudcasts.net so they don’t break if I move it to another platform.

BizTalk Server Orchestration Performance Webcast
I’ve just uploaded the second in a series of webcasts looking at calling web services from an orchestration in BizTalk Server 2009 to BloggersGuides.net. This one will start were the last webcast left off, and will look at improving the performance and lowering the latency of the orchestration.

I’ll be starting with a basic one looking at calling WCF services from an orchestration using the Service Aggregator pattern, and then look at improving the design to make it more efficient and reliable in future webcasts. This webcast will look at implementing a service aggregator pattern to call three WCF services that will book a hotel, flight and conference for ......
