DESCRIPTION
It's easy for developers to get enthusiastic about how simple it seems to implement an event-driven architecture with NServiceBus. Reality, however, can be quite different. Chances are you won't be able to start a new green field project to do this. Instead you'll need to add small pieces to your existing systems step-by-step and, hopefully, migrate to the new target architecture over a longer period. Jan Ove Skogheim shows how Rikstoto, the only licensed horse racing operator in Norway, moved from a layered service platform with Web Services calling other Web Services to a fully scaled out event driven platform based on NServiceBus.
