How does the concept of “service registry” work in a microservices

rchitecture?

service registry is a centralized directory of available services and their instances. It

helps microservices locate and communicate with each other.

How it works:

• Each microservice registers itself with the service registry when it starts, providing

metadata like its IP address, port, and health status.

• Other microservices query the registry to discover and connect to the required

service.

• Service registries also support health checks, ensuring that only healthy services

re discoverable.

Tools: Examples of service registries include Consul, Eureka, and Zookeeper.
