What is Service Discovery?
The mechanism by which microservices find and communicate with each other. Services register themselves and others can look them up by name.
Service Discovery is a intermediate-level concept that sits in the Microservices Architecture area of system design. Engineers reach for it whenever they need to reason about real-world trade-offs in that space — not just for textbook correctness, but because real production systems at companies like Netflix, Amazon, and Google make these decisions every day.
If you want to go deeper than this definition — with diagrams, code, and a quiz to lock it in — work through the "Service Discovery" lesson linked below. It walks through the why, the mechanism, the trade-offs, and how the giants actually use it in production.
