patterns & practices team recently released the 3rd guidance in Windows Azure series. The goal of this guide is to map Windows Azure features with the specific challenges encountered in the hybrid application scenario. Windows Azure now offers a number...

The number of CPU core under your account is limited to 20 by default. If you see a red box like this, it could hit this limit. This limit is applied to # of CPU core, not # of instances. You can calculate the number by adding up CPU cores for each instance...

If you see web roles or worker roles are going back and forth between initializing-busy-stopping, the first thing you should check is the copy local attribute of the assemblies. All assemblies that aren’t part of .NET framework have to be set as Copy...

In dev fabric, hit F5, wait for a while then start debugging. No wonder if your worker roles don’t respond in the first place. Sometimes it takes over 30 seconds for them to start off. You should better check the dev fabric UI. When it looks like this...

To explore further the way context-aware services can be implemented and integrated into large communities, let’s travel a short distance into the future, to a time when the ideas in this article have borne fruit in the real world, and consider...

User context is the mechanism by which service providers connect consumption with delivery in a user-centric way. Journalists adhere to a maxim commonly called five Ws and an H . According to this principle, a complete and proper news story must answer...

At the previous post, I wrote a picture below to illustrate the architecture for consumer oriented services. Now let me explain each architectural elements as follows.   Propagation Architecture The propagation architecture concerns the mechanisms...

From a service provider’s perspective, there are a few principles to keep in mind when envisioning and building architecture: 1.     You go to them . Building consumer oriented services involves standing the traditional view of the...
