Meetup JUG.CY July 21 with Nicolas Frankel, Apache APISIX

There will be two technical topics on meetup and of course, you can ask questions of our guests and have a lot of networking.

Participation is completely free, but places are limited, please check in if you plan to attend the meeting, we can't let you into the building if you are not on the list.

Evolving your APIs, a pragmatic approach
When you publish your first HTTP API, you’re more focused on short-term issues than planning for the future. However, chances are you’ll be successful, and you’ll “hit the wall”. How do you evolve your API without breaking the contract with your existing users?

In this talk, Nicolas will first show you some tips and tricks to achieve that: moving your endpoints, deprecating them, monitoring who’s using them, and letting users know about the new endpoints. The talk is demo-based, and I’ll use the Apache APISIX project for it.

Practical introduction to OpenTelemetry tracing
Tracking a request’s flow across different components in distributed systems is essential. With the rise of microservices, their importance has risen to critical levels. Some proprietary tools for tracking have been used already: Jaeger and Zipkin naturally come to mind.

Observability is built on three pillars: logging, metrics, and tracing. OpenTelemetry is a joint effort to bring an open standard to them. Jaeger and Zipkin joined the effort so that they are now OpenTelemetry compatible.

In this talk, Nicolas will describe the above in more detail and showcase a (simple) use case to demo how you could benefit from OpenTelemetry in your distributed architecture.
