Learn how to implement distributed tracing and observability in Node.js microservices using OpenTelemetry and Grafana Tempo β from local Docker setup to Grafana Cloud deployment. π¬ Today, we build a **real-world cloud observability system** for Node.js microservices β starting from **local Docker-based tracing** and progressing to **full cloud-native distributed tracing** using **OpenTelemetry and Grafana Tempo**. You will see **exactly how production systems are observed**, how trace context flows across services, and how engineers debug real microservices using **Grafana Explorer and Drilldown views**. ββββββββββββββββββββββββββββββββββββ π§© **PROJECTS & MODULES INCLUDED** ββββββββββββββββββββββββββββββββββββ β API Gateway (trace root) β Authentication microservice β Protected Order microservice β Distributed tracing implementation β Local observability stack (Docker + Grafana) β Cloud observability setup (Grafana Cloud) β End-to-end trace propagation β Real client simulation workflow ββββββββββββββββββββββββββββββββββββ π *GITHUB SOURCE CODE* π https://github.com/shafqatgreat/cloud-observability π *Daily Dev Post* π https://app.daily.dev/posts/xoLLkxgy1 ββββββββββββββββββββββββββββββββββββ π **ARCHITECTURE BUILT IN THIS TUTORIAL** ββββββββββββββββββββββββββββββββββββ Client β API Gateway (Cloudflare Workers) β Auth Service (Railway) β Order Service (Railway) β Grafana Tempo (Local & Cloud) All requests flow through the gateway β no service is accessed directly.
