The benefits of modeling data as events as a mechanism to evolve our software systems. This meant a lot of time was spent on things like cycle time analysis, build pipeline design, test automation, and infrastructure automation. Enter streams of events, specifically the kinds of streams that technology like Kafka makes possible.

Capturing data is critical to understanding how your applications and infrastructure are performing at any given time. Logs are important because you’ll naturally want an event-based record of any notable anomalies across the system. Metrics originate from several sources including infrastructure, hosts, and third-party sources.
