SPRING CLOUD | Notion

Spring Cloud is a framework that provides tools to build distributed systems and microservices in the Spring ecosystem.

It adds features to handle service discovery, configuration management, load balancing, API gateways, messaging, and more.
Works well with Spring Boot to simplify distributed system complexity.

💡 Think of it as a toolbox for solving common challenges in cloud-native and microservices architectures.

Why use Spring Cloud?

Spring Cloud helps in:

Centralized Configuration Management → Manage all microservices’ configs in one place.
Service Discovery → Dynamically find and call services (Eureka, Consul).
Load Balancing → Distribute requests across multiple service instances.
Fault Tolerance → Retry, circuit breaker, and fallback support.
API Gateway → A single entry point to all backend services.
Cloud-Ready → Works with AWS, Azure, GCP, Kubernetes, etc.
