Spring Cloud Service Communication Methods

In Spring Cloud, service-to-service communication is typically implemented using RestTemplate or Feign. RestTemplate is a template class provided by the Spring framework for accessing RESTful services, allowing for sending HTTP requests and handling responses. Feign, on the other hand, is a declarative HTTP client that simplifies service communication by defining interfaces and annotations. Additionally, Spring Cloud offers components like Ribbon and Eureka for load balancing and service discovery, making it easier for developers to build microservices architecture.
