Simplifying our n-tier development platform: making 3 things 1 thing

As you’ve probably observed, we’ve been working hard over the past year or so to grow our application stacks to better support the types of applications (Silverlight, rich desktop, AJAX, etc) and services (SOAP, REST, etc) that are required to build modern, robust solutions.  At present, a few of the technologies we have to help… Read more

Astoria futures: offline-enabled data services

Now we’ve been working on various design aspects of Data Services for its future versions, and synchronization/offline support is one of them. It’s still an experimental thing with no official… Read more

URI Format – Part 1 – Addressing resources using URI path segments

Deciding on something that becomes a public interface of a developer-oriented technology is a tricky task. Not only does the resulting design need to be correct and complete, but also there are various aspects that are more around aesthetics and personal preference. The URI format used by Astoria will need to survive both sets of… Read more

Astoria Design: payload formats

The goal of Astoria is to make data available to loosely coupled systems for querying and manipulation. In order to do that we need to use protocols that define the interaction model between the producer and the consumer of that data, and of course we have to serialize the data in some form that all… Read more

We have been looking at various options to ensure that the design of Astoria truly reflects the requirements of the day to day challenges that our developer community faces when building real-world web applications and services. We would like to start by being as transparent as possible in the design process. I wanted to briefly… Read more
