Can you list the main components of Spring Cloud and briefly describe their functions?

Spring Cloud is a set of tools for developing distributed systems and microservices based on Spring Boot. Main components:

• Spring Cloud Config — centralized management of application configurations.
• Eureka — service discovery, which allows microservices to find each other.
• Ribbon — client-side load balancer for distributing requests among service instances.
• Feign — declarative HTTP client to simplify REST service calls.
• Hystrix — library for implementing the Circuit Breaker pattern, increasing system resilience.
• Zuul — API Gateway that routes and filters requests to microservices.
• Spring Cloud Bus — for propagating configuration events and other messages between services.

These components help simplify development, scaling, and management of microservice architecture.
