For example, without investment, visibility into system behavior as a whole can be much more difficult in an event-driven system. Investing in something like Open Telemetry and a service catalog is a good idea.  Getting started with these things are relatively simple, but if you want to store your traces somewhere that are searchable, you are going to have to either pay for a SaaS tool that ingests them or you are going to have to run and maintain an open source tool capable of this such as Jaeger. For service cataloging, Backstage is becoming a very popular option.   Depending on the capabilities and the capacity of your engineering team, this might be a good option and many companies do have platform teams that provide tooling such as this. With the average salary of a platform Engineer being ~$144k, companies should think carefully on whether the benefits of an EDA are going to outweigh the cost. We will dig deeper into this in part 2 and 3 of the series.

Distributed Tracing: Middleware for distributed tracing like Jaeger and Zipkin helps monitor and trace requests as they flow through multiple microservices, aiding in debugging, performance optimization, and understanding the system's behavior.

From here, we can explore other developments and tutorials on Kubernetes, such as o11y or observability (PLG, ELK, ELF, TICK, Jaeger, Pyroscope), service mesh (Linkerd, Istio, NSM, Consul Connect, Cillium), and progressive delivery (ArgoCD, FluxCD, Spinnaker).

After reading this blog post, you will learn how to instrument a basic Node.js Lambda function using OpenTelemetry to provide better insights into what the code is doing, store the tracing data in Jaeger where you can visualize and query the information and run trace-based testing with Tracetest to include automated validations based on the generated telemetry data.

I love the log Factory pattern that Jaeger uses. https://github.com/jaegertracing/jaeger/blob/main/examples/hotrod/pkg/log/factory.go

Thanks for your reply! Pretty much running into all these issues stated here: https://github.com/jaegertracing/jaeger/issues/3571

Otro servicio open source para tracing es Jaeger que sí soporta OpenTelemetry

Now that Quickwit is an official Jaeger backend, we have published a step-by-step guide to tracing your Node.js application using Quickwit and Jaeger. https://quickwit.io/blog/quickwit-as-official-jaeger-backend
