Performance testing of microservices in action
summary
Walks through performance analysis of a simple calculator implemented as microservices, and demonstrates a FOSS toolchain for testing and profiling. It uses k6 and Gatling for load generation, Prometheus for monitoring, Linux perf for profiling, and FlameGraph for visualizing hot paths to pinpoint IPC and microservice-related performance issues.
