In this chapter, we took a deeper dive into Software as a Service (SaaS) and how NServiceBus ties into cloud computing. We had a very brief introduction to the cloud and some of its services. We discussed the Azure Storage Services and Azure Service Bus as they apply to providing persistence and message queues. Visual Studio has many tools for building applications both on-premise and in the Azure cloud. We walked through a sample in each, where we stored all the timeouts, saga, and subscription information in Azure.
