Ribbon
Ribbon est un équilibreur de charge côté client et une bibliothèque de communication RPC conçue pour la communication inter-processus. Il fonctionne comme un proxy réseau tolérant aux pannes qui distribue les requêtes réseau sortantes à travers un pool d'instances de serveur disponibles pour éviter la surcharge des nœuds.
Le projet s'intègre en tant que client de découverte de service, maintenant des listes synchronisées d'instances de serveur disponibles en se connectant avec des outils de découverte d'environnement cloud. Cela lui permet de gérer les tentatives de requête et le comportement de basculement lorsque les serveurs distants ne répondent plus.
La bibliothèque prend en charge une couche de transport agnostique au protocole pour la communication HTTP, TCP et UDP. Elle gère en outre le trafic réseau via la tolérance aux pannes par disjoncteur (circuit-breaker), des schémas de sérialisation enfichables, et le traitement par lots et la mise en cache des requêtes pour réduire la surcharge.
Features
- Client-Side Load Balancing - Provides client-side logic to distribute network requests across multiple available server instances.
- Service Discovery Clients - Implements a client that resolves service names from cloud registries to route requests to available instances.
- Inter-Process Communication - Enables inter-process communication via asynchronous remote procedure calls across diverse network protocols.
- Fault Tolerant Network Proxies - Acts as a fault-tolerant network proxy managing request retries and failover behavior.
- Multi-Protocol Transport Abstraction - Implements a unified interface to manage asynchronous communication across different network transport protocols.
- Protocol-Agnostic Transport Layers - Provides a transport layer abstraction that supports multiple protocols including HTTP, TCP, and UDP.
- Remote Procedure Calls - Facilitates the execution of remote procedure calls distributed across multiple server instances.
- RPC Frameworks - Provides a full framework for executing asynchronous remote procedure calls over HTTP, TCP, and UDP.
- Service Discovery Integrations - Integrates with external cloud registries to synchronize and maintain lists of healthy server instances.
- Circuit Breakers - Implements circuit breakers to stop traffic to unresponsive remote server instances and prevent cascading failures.
- Fault Tolerance - Manages failure handling and request retries to ensure resilience in distributed service communication.
- Dynamic Instance Synchronization - Maintains an accurate, synchronized list of available server instances via service discovery tools.
- Server Request Load Balancers - Distributes outgoing network requests across a pool of servers using load balancing algorithms.
- Batch Request Optimizations - Optimizes request performance by batching multiple API calls to reduce network round-trips.
- Pluggable Serialization - Ships a pluggable architecture for interchangeable encoders to handle various REST and RPC payloads.
- Request Batching - Reduces network overhead by grouping multiple remote procedure calls into single executions.
