Streaming and eventing are two architectural styles based on event-driven architecture. Although both contribute to building asynchronous, scalable, and decoupled applications, a few differences exist in their approaches.

The first half of this talk compares and contrasts eventing and streaming across a few dimensions, including event delivery semantics, retention, selective event subscription, and processing patterns. Additionally, several real-world use cases will be discussed for each.

While streaming and eventing have their differences, they can co-exist to fill each other's gaps, enabling you to build even better solutions by combining them. The second half of the talk discusses a practical use case related to event-driven Microservices, which combines both the eventing and streaming features to build a scalable and reliable operational system.
