Cloudflare har annonceret \u00e5bningen af kildekoden til Pingora-rammen, der er designet til udvikling af sikre, h\u00f8jtydende netv\u00e6rkstjenester og programmerbare netv\u00e6rkssystemer ved hj\u00e6lp af Rust. Rammen er godt testet og er allerede i brug i h\u00f8jbelastede systemer \u2014 en proxy bygget p\u00e5 den har v\u00e6ret i drift i over et \u00e5r i Cloudflares indholdsleveringsnetv\u00e6rk i stedet for nginx og h\u00e5ndterer mere end 40 millioner anmodninger i sekundet. Koden er skrevet i Rust og offentliggjort under Apache 2.0-licensen. <\/p>\n

Pingora kan bruges til multithreading behandling af foresp\u00f8rgsler i asynkron tilstand, underst\u00f8tter HTTP\/1 og HTTP\/2 (HTTP\/3 er p\u00e5 vej), gRPC og WebSocket proxiering, tilsluttede belastningsbalancere, \u00e6ndring af konfiguration uden genstart, kodeopdatering uden afbrydelse af forbindelser, fasts\u00e6ttelse af belastningsskiftstrategi i tilf\u00e6lde af fejlsikring, integration med forskellige overv\u00e5gnings- og logningssystemer (Syslog, Prometheus, Sentry, OpenTelemetry). TLS-kryptering underst\u00f8ttes ogs\u00e5 i Pingora, men det er implementeret som et lag oven p\u00e5 C-bibliotekerne OpenSSL og BoringSSL. <\/p>\n

Der tilbydes klar-til-brug Rust-pakker til oprettelse af HTTP-proxier, arbejde med netv\u00e6rksprotokoller, parsing af HTTP-header, trafikoverv\u00e5gning og -begr\u00e6nsning, belastningsbalancering, arbejde med distribueret hash-tabel Ketama, vedligeholdelse af cache i RAM og asynkron behandling af timeout. Udover HTTP underst\u00f8ttes oprettelse af tjenester, der bruger egne protokoller eller UDP\/TCP. <\/p>\n

Et n\u00f8gleprioritet for projektet er at sikre sikkerhed \u2014 for at reducere sandsynligheden for fejl relateret til hukommelsesarbejde blev Rust valgt som udviklingssprog. Der er ogs\u00e5 lagt stor v\u00e6gt p\u00e5 effektivitet, ydeevne og skalerbarhed. For eksempel ved oprettelsen af en proxy-servere<\/a> og belastningsbalancere baseret p\u00e5 Pingora, er der mulighed for at knytte callback-h\u00e5ndteringsrutiner og filtre, der muligg\u00f8r styring af forskellige stadier af foresp\u00f8rgselsbehandlingen samt \u00e6ndre, omdirigere, blokere og logge foresp\u00f8rgsler og svar. <\/p>\n

Sammen med organisationen ISRG (Internet Security Research Group), som er stifter af projektet Let's Encrypt og fremmer teknologier til at forbedre internetsikkerhed, vil der blive oprettet en omvendt proxy ved navn River baseret p\u00e5 Pingora, designet til brug i kritiske elementer. af netv\u00e6rksinfrastruktur<\/a>. Koden til River vil blive skrevet i Rust og distribueret under Apache 2.0 licensen. Udviklingen starter i andet kvartal af 2024. Projektet er i \u00f8jeblikket i fase med design og arkitektur. Projektet udvikles under ledelse af James Munns fra Rust Embedded Working Group. <\/p>\n

Hovedform\u00e5let med River-projektet er at implementere en proxy, der kan videresende klientanmodninger til backend-servere, terminere indkommende TLS-forbindelser og rute, \u00e6ndre og filtrere anmodninger i henhold til de fastsatte regler. River n\u00e6vner en multithreaded anmodningsbehandlingsmodel, der muligg\u00f8r mere effektiv genbrug af forbindelser sammenlignet med proxy'er som nginx. For at udvide proxyens funktionalitet og skabe filtre vil der blive underst\u00f8ttet tilslutning af moduler kompilering i WebAssembly-format (hvilket betyder, at der kan anvendes ethvert programmeringssprog, der underst\u00f8tter kompilering til WASM). Konfigurationsformatet planl\u00e6gges at v\u00e6re s\u00e5 simpelt og intuitivt som muligt.
