How to make your SpringBoot Microservices scalable with WebFlux, Blocking vs Reactive benchmarking

This demo is a simulation of a real problem we experienced in a production system where we had several core monolith with some proxy microservices on top of them. The system had total failures sometimes when only one of the core systems experienced some performance spikes. After some research, we found very interesting behavior and wanted to share the outcome of the load test and results in this video.

Short but good enough code example to express the benefits of reactive API ! Thank you for your presentation!
