How does the concept of “service registry” work in a microservices architecture?
A 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.
Follow :
- Other microservices query the registry to discover and connect to the required
service.
- Service registries also support health checks, ensuring that only healthy services
are discoverable.
Tools: Examples of service registries include Consul, Eureka, and Zookeeper.
