"Conduit.com uses NServiceBus for messaging between the systems that serve their over 200 million users and running millions of installation processes every day. NServicebus framework was embedded in several conduit.com subsystems. The framework proved itself as a reliable and robust infrastructure for our runtime load-intensive production distributed environment. NServicebus is straightforward to use, easy to configure and adapt for specific needs and contains great features (Saga, Distributer and more) that are very useful and powerful."
"Rackspace is migrating away from a large, monolithic code-base to an NServiceBus-based solution in their Email & Apps division. "The main benefit NServiceBus has brought us so far is developer scalability due to lower coupling and higher consistency in our code."
