MSDN Magazine Smart Client Article
2009-03-28 20:16:00 My article on ?optimizing a large-scale Software+Services application? has been published in the April edition of MSDN Magazine. Here?s a short excerpt: ?We had to juggle occasional connectivity, data synchronization, and publish/subscribe all at the same time. We learned that we couldn’t solve all problems either client-side or server-side, but rather that an integrated approach was needed ...
Messaging ROI
2009-02-22 11:12:00 There’s been some recent discussion as to the “cost” of messaging: Greg Young asserts: “I believe that this shows there to be a rather negligible cost associated with the use of such a model. There is however a small cost, this cost however I believe only exists when one looks at the system in isolation.” Ayende adds ...

Scalability of Impact Attenuator Testing
2009-01-11 20:42:00 Greetings all, As part of my university's Formula SAE, we are trying to develop a way to test the 'crush foam' (aluminium honeycomb structure, with cells having an approximate diameter of 8mm) to fix to the nose of the car. (To get an idea of the application, check out http://www.fsae.com/

Building Super-Scalable Web Systems with REST
2008-12-29 22:38:00 I’ve been consulting with a client who has a wildly successful web-based system, with well over 10 million users and looking at a tenfold growth in the near future. One of the recent features in their system was to show users their local weather and it almost maxed out their capacity. That raised certain warning ...

SOA, REST, and Pub/Sub
2008-12-15 09:34:00 From Integrated Simplicity: The question of how web-based (or 3rd party) consumers can work with pub/sub based services comes up a lot. Many developers are used to implementing web services exposing methods on them like GetAllCustomers. When moving to pub/sub and other more loosely coupled messaging patterns, developers look to implement the same pattern, opting for something ...

What is Scalability Testing?
2008-10-14 12:04:00 Scalability Testing is used to check whether the functionality and performance of a system are capable to meet the volume and size change as per the requirements.Scalability testing can be done using load test with various software and hardware configurations changed, where the testing environment settings unchanged.
