API Gateway with Spring Cloud Gateway
Build an API Gateway using Spring Cloud Gateway to route requests, handle security, and manage cross-cutting concerns.
API Gateway: The Front Door
In a microservices architecture, you often have many small, independent services. How do client applications (like a mobile app or web browser) interact with them?
An API Gateway acts as a single, unified entry point for all client requests. Instead of clients needing to know about and call individual services, they simply communicate with the gateway.
Why Use an API Gateway?
Gateways centralize common functionalities that would otherwise be duplicated across multiple services or handled by clients. This simplifies development and enhances service management. Key benefits include:
- Request Routing: Directing incoming requests to the correct backend microservice.
- Security: Handling authentication and authorization at the edge.
- Rate Limiting: Protecting services from being overwhelmed by too many requests.
- Monitoring & Logging: Centralized collection of request metrics and logs.
- Circuit Breaking: Improving resilience against failures in downstream services.
