Spring Cloud Gateway
Spring Cloud Gateway es una puerta de enlace de API y servicio de enrutamiento construido sobre Spring Boot. Actúa como un punto de entrada central para microservicios, dirigiendo el tráfico HTTP entrante a servicios downstream utilizando una combinación de predicados y filtros.
El proyecto es un enrutador de solicitudes no bloqueante que aprovecha Netty y Project Reactor para manejar tráfico de alta concurrencia mediante flujos de datos asíncronos. Funciona como un enrutador de solicitudes dinámico y filtro de tráfico de red, permitiendo la detección automatizada y el enrutamiento a instancias de servicio disponibles en entornos de red dinámicos.
La puerta de enlace gestiona el tráfico de microservicios mapeando solicitudes basadas en rutas, métodos, encabezados o criterios de host. Proporciona capacidades para la modificación del tráfico de red, lo que incluye la reescritura de rutas URL y la alteración de encabezados de solicitud y respuesta a través de un pipeline de filtros.
Features
- Microservice Traffic Management - Functions as a central entry point for routing and balancing traffic between distributed microservices.
- Gateway-Based Request Routings - Acts as an external entry point that applies authentication, rate limiting, and path rewriting before forwarding to microservices.
- Spring Cloud Implementations - Implements the API gateway pattern as part of the Spring Cloud ecosystem for routing and service discovery.
- API Gateways - Provides a full API gateway implementation for routing external requests to internal microservices.
- Service Discovery - Provides mechanisms for dynamically locating and routing to service instances in elastic microservices environments.
- Registry-Based Service Discovery - Employs a registry-based discovery pattern to track and resolve dynamic service member addresses.
- Dynamic Service Discovery - Resolves logical service names into physical network addresses in real-time for microservices communication.
- Network Traffic Routing - Directs incoming network requests to specific backend services as a single entry point for all traffic.
- Network Traffic Transformers - Modifies network headers, parameters, and paths in real-time using a pipeline of filters.
- Asynchronous Data Streams - Processes network requests as asynchronous data streams using Project Reactor's Flux and Mono.
- Request Routers - Intercepts and forwards network requests based on dynamic rules including paths, methods, headers, or host criteria.
- Request and Response Transformations - Implements a pipeline of filters to rewrite URL paths and alter request and response headers.
- Traffic Routing - Directs HTTP requests to downstream services based on path, method, header, or host criteria.
- Request and Response Filters - Provides a sequence of filters to alter request and response headers and rewrite paths.
- Non-blocking I/O - Utilizes non-blocking I/O and an event-loop model to handle high-concurrency network traffic.
- Request-Response Filter Chains - Implements a modular sequence of interceptors to mutate and validate request and response traffic.
- Predicate-Based Request Filtering - Evaluates configurable boolean predicates to conditionally dispatch incoming HTTP requests to backend services.
- Service Discovery Integrations - Integrates with discovery clients to dynamically locate microservice instances without hardcoded addresses.
- Asynchronous Request Routers - Leverages Netty and Project Reactor as a high-performance engine for mapping traffic to concurrent handlers.
- Dynamic Service Mapping - Maps incoming HTTP requests to downstream services based on the runtime evaluation of paths and headers.
- Request Path Rewriters - Provides utilities for rewriting URL paths and modifying headers before they reach backend services.
- Tiered Route Filters - Provides a tiered filtering architecture that separates global interceptors from route-specific logic.
- Service Discovery Integrations - Integrates with external naming services and registries to automatically detect and route to available service instances.
- Request and Response Transformers - Modifies data payloads and headers during the request and response lifecycle via filter chains.
- API Gateways - Routing and filtering solution for the Spring ecosystem.
