La soci\u00e9t\u00e9 Cloudflare a annonc\u00e9 l'ouverture du code source du framework Pingora, con\u00e7u pour le d\u00e9veloppement en Rust de services r\u00e9seau s\u00e9curis\u00e9s et performants, ainsi que de syst\u00e8mes r\u00e9seau programmables. Ce framework est bien test\u00e9 et est d\u00e9j\u00e0 utilis\u00e9 dans le fonctionnement de syst\u00e8mes \u00e0 forte charge \u2014 un proxy bas\u00e9 sur celui-ci a \u00e9t\u00e9 utilis\u00e9 pendant plus d'un an dans le r\u00e9seau de diffusion de contenu de Cloudflare au lieu de nginx et traite plus de 40 millions de requ\u00eates par seconde. Le code est \u00e9crit en Rust et publi\u00e9 sous la licence Apache 2.0. <\/p>\n

Pingora peut \u00eatre utilis\u00e9 pour le traitement multithread des requ\u00eates en mode asynchrone, prend en charge HTTP\/1 et HTTP\/2 (HTTP\/3 est pr\u00e9vu), le proxy gRPC et WebSocket, les \u00e9quilibres de charge modulaires, la modification de configuration sans red\u00e9marrage, la mise \u00e0 jour du code sans rupture de connexion, la d\u00e9finition de strat\u00e9gies de basculement en cas de d\u00e9faillance, ainsi que l'int\u00e9gration avec divers syst\u00e8mes de surveillance et de journalisation (Syslog, Prometheus, Sentry, OpenTelemetry). TLS est \u00e9galement pris en charge dans Pingora, bien qu'il soit mis en \u0153uvre comme une extension des biblioth\u00e8ques C OpenSSL et BoringSSL. <\/p>\n

Des packages Rust pr\u00e9configur\u00e9s sont fournis pour la cr\u00e9ation de proxies HTTP, le travail avec des protocoles r\u00e9seau, l'analyse des en-t\u00eates HTTP, le suivi et la limitation du trafic, l'\u00e9quilibrage de charge, le travail avec une table de hachage distribu\u00e9e Ketama, la mise en cache en m\u00e9moire et le traitement asynchrone des d\u00e9lais d'attente. En plus de HTTP, il est \u00e9galement possible de cr\u00e9er des services utilisant leurs propres protocoles ou UDP\/TCP. <\/p>\n

La s\u00e9curit\u00e9 a \u00e9t\u00e9 d\u00e9sign\u00e9e comme la priorit\u00e9 cl\u00e9 du projet \u2014 pour r\u00e9duire le risque d'erreurs li\u00e9es \u00e0 la gestion de la m\u00e9moire, le langage Rust a \u00e9t\u00e9 choisi pour le d\u00e9veloppement. Une attention particuli\u00e8re a \u00e9galement \u00e9t\u00e9 port\u00e9e \u00e0 l'efficacit\u00e9, aux performances et \u00e0 l'\u00e9volutivit\u00e9. Par exemple, lors de la cr\u00e9ation du proxy-serveurs<\/a> et d'\u00e9quilibres de charge bas\u00e9s sur Pingora, la possibilit\u00e9 d'attacher des gestionnaires de rappel et des filtres est pr\u00e9vue, permettant de g\u00e9rer diff\u00e9rentes \u00e9tapes du traitement des requ\u00eates, ainsi que de modifier, rediriger, bloquer et journaliser les requ\u00eates et r\u00e9ponses. <\/p>\n

En collaboration avec l'organisation ISRG (Internet Security Research Group), qui est le fondateur du projet Let's Encrypt et qui favorise le d\u00e9veloppement de technologies pour am\u00e9liorer la s\u00e9curit\u00e9 d'Internet, un proxy invers\u00e9 River sera construit sur la base de Pingora, destin\u00e9 \u00e0 \u00eatre utilis\u00e9 dans des \u00e9l\u00e9ments critiques. de l'infrastructure r\u00e9seau<\/a>. Le code de River sera \u00e9crit en Rust et distribu\u00e9 sous la licence Apache 2.0. Le d\u00e9veloppement commencera au deuxi\u00e8me trimestre de 2024. Actuellement, le projet est en phase de conception et de d\u00e9finition de l'architecture. Le projet est dirig\u00e9 par James Munns de la Rust Embedded Working Group. <\/p>\n

L'objectif principal du projet River est de mettre en \u0153uvre un proxy capable de transmettre les requ\u00eates des clients aux serveurs backend, en terminant les connexions TLS entrantes et en routant, modifiant et filtrant les requ\u00eates selon des r\u00e8gles d\u00e9finies. Parmi les caract\u00e9ristiques de River, on mentionne un mod\u00e8le de traitement des requ\u00eates multithread\u00e9, permettant un r\u00e9emploi des connexions plus efficace par rapport \u00e0 des proxies tels que nginx. Pour \u00e9tendre les fonctionnalit\u00e9s du proxy et cr\u00e9er des filtres, la connexion de modules compil\u00e9s au format WebAssembly sera prise en charge (tout langage de programmation capable de compilation en WASM pourra \u00eatre utilis\u00e9 pour le d\u00e9veloppement). Le format de configuration sera con\u00e7u pour \u00eatre aussi simple et familier que possible.
