Explanation

An API Gateway acts as the single entry point for all client requests in a microservices architecture.

Code:

Client
   |
API Gateway
   |
Microservices

Explanation

Spring Cloud Gateway routes incoming requests to the appropriate microservice.

Code:

spring:
  cloud:
    gateway:
      routes:

Explanation

Eureka Server is used for service discovery. Microservices register themselves automatically.

Code:

@EnableEurekaServer
@SpringBootApplication
public class EurekaServer{}

Explanation

Each microservice registers with Eureka using its application name.

Code:

spring.application.name=student-service
eureka.client.service-url.defaultZone=http://localhost:8761/eureka

Explanation

The API Gateway uses service discovery to route requests without hardcoding server addresses.

Code:

lb://student-service
lb://course-service
