With the dawn of microservices and serverless, event-driven architectures have become the way to go when building a new system in the cloud. This approach has allowed for greater scalability, as the system can easily adapt and respond to changes in traffic or demand without having to overhaul the entire architecture. Additionally the Event-driven approach means your application is mainly concerned with routing event data to the right services.

Instrumenting your code is essential to understanding your system’s performance and diagnosing issues as they arise. Traditionally, this was accomplished using proprietary vendor libraries, causing major lock-in. Enter OpenTelemetry. OpenTelemetry is an open-source project that provides a set of APIs, SDKs, and integrations for instrumenting code.
