Observability for Microservices

Welcome to observing microservices! Microservices break down large applications into smaller, independent services. This brings many benefits, but also unique challenges for understanding system behavior.

Instead of one big application, you now have many small ones, all talking to each other. How do you keep track?

In a microservices architecture, a single user request might travel through dozens of different services, each running on its own server or container. This distributed nature creates several observability hurdles:

• Lost in Translation: It's hard to follow a request's journey end-to-end.
• Debugging Nightmare: Pinpointing the exact service causing an issue becomes complex.
• Inter-service Communication: Understanding how services interact and depend on each other is crucial.
