Distributed Tracing Concepts

In a microservices world, a single user request can involve many different services talking to each other. It's like a relay race!

But what happens if one part of this race is slow, or fails entirely? How do you find the exact point of failure or bottleneck?

Distributed tracing is a technique that lets you follow the path of a single request as it travels through all the different services in your system.

It gives you a detailed 'journey map' for every request, showing you exactly where it went and what happened at each stop.
