Just like on-premises applications, the availability for cloud applications needs to be carefully planned. In this blog post I’ll discuss different levels of availability for Windows Azure-hosted applications. Ultimately the level of availability you choose needs to be a business decision that balances cost with your personal tolerance for the nines. To guide us though this discussion, I’ll use a typical Windows Azure application as an example. The architecture of our sample application consists of three primary components: Windows Azure […]

As a Microsoft partner with several gold competencies and cloud memberships, we are entitled to an extensive suite of internal use licenses for many of Microsoft’s on-premise and cloud products.  During our recent rollout of Office 365, the elegance of Microsoft’s long-term vision of federating authentication (which has been evolving since the release of Active Directory Federation Services (ADFS) 1.0 in 2005) really stood out.

In this blog post we will look at a few compelling […]

When it comes to building distributed systems, one of the most important patterns is the message broker. But what’s a message broker? A message broker is an architectural pattern for message validation, message transformation and message routing. It mediates communication amongst applications, minimizing the mutual awareness that applications should have of each other in order to be able to exchange messages, effectively implementing decoupling. The practical utility of this construct has been proven in many distributed systems over the years.  Within the […]
