9. Connecting to Azure Event Hubs

Event-based integration is a key pattern for implementing microservices. The idea of a microservices architecture is to decompose a monolithic application into a smaller set of services. Events are commonly used to coordinate between these different services. When you think about an event, it can be one of many things. Financial transactions can be an event, as well as IoT sensor data, web page clicks and views, and much more.
