Advanced Topic 37 of 51 Distributed Systems & Cloud
Service Discovery
Locating service instances dynamically.
How it works
Services register addresses in a registry (Consul, etcd, Kubernetes DNS) so clients find healthy instances dynamically, using client-side or server-side load balancing.
Where it is used
Microservices with changing IPs.
Common pitfall
Stale registrations route to dead instances.
Where it fits in the course
Service Discovery is topic 37 of 51 in Distributed Systems & Cloud, rated Advanced. It follows Apache Spark. The next topic is API Gateway.
