Scaling Out With Object-Relational Mapping on .NET  : Page 2

The Sample Application

The tested application was a slightly modified version of Pragmatier PetMarché, an enterprise e-commerce application written in VB.NET. It shall be noted that the application would have to be slightly modified in a real world case to integrate it with existing IT-infrastructure and to add better security and stronger monitoring capabilities. Implemented properly, none of these extensions would affect the scalability of the application.

The shopping cart was stored in a shared session state server to allow Network Load Balancing (NLB) with network client affinity turned off. Each request was dynamically routed to a new server regardless of which server handled the previous request allowing fail-over and symmetric load balancing.
