In this chapter, we discussed how we can utilize the Service Bus to disconnect our application components and communicate between the different tiers of our application. We discussed how we can create and send messages through Service Bus Queues and Topics and when we would use each. Lastly, we discussed patterns for the use of these Azure components.

In the next chapter we will discuss how to create hybrid applications where the frontend of the application runs in the Azure cloud while line-of-business or database systems remain and run on-premises.
