Spring Cloud is a suite of tools designed to facilitate the development of cloud-native applications using the Spring framework. It provides developers with a set of features that simplify the process of building distributed systems, enabling them to manage microservices effectively. Key functionalities include service registration and discovery, load balancing, circuit breakers, and configuration management. By leveraging Spring Cloud, developers can create resilient and scalable applications that can easily adapt to the dynamic nature of cloud environments. This framework enhances the capabilities of Spring and Spring Boot, making it easier to implement microservices architecture in modern applications.
