spring-cloud/spring-cloud-gateway

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.
