Overview
I wanted to actually understand enterprise backend infrastructure - not just read about it, but build it from scratch. FlowOps is a gamified simulator that walks you through four progressive challenges, each one building on the last.
Challenge 1 is API gateway routing with WSO2 API Manager. Challenge 2 adds rate limiting and throttling policies. Challenge 3 introduces Kafka event streams for async processing. Challenge 4 ties it all together with live Prometheus + Grafana telemetry dashboards. Each challenge has pass/fail criteria - you can't move forward until your infrastructure actually works.
The entire stack runs in Docker containers orchestrated with GitLab CI/CD, and every component is instrumented for observability.
