What is service discovery in microservices architecture?
Answer:
Explanation:
Service discovery is a key concept in microservices architecture that allows services to find and communicate with each other dynamically. In a distributed system, the number of service instances and their locations can change frequently due to scaling, updates, or failures. Service discovery automates the process of locating services, ensuring that each service can find and interact with others without hardcoding their locations.
Typically, a service registry like Netflix Eureka or Consul is used to manage this process. Services register themselves with the registry, which keeps track of their locations. Other services can query the registry to find the instances they need to communicate with, allowing the system to remain resilient and adaptable to changes.
