A empresa Cloudflare anunciou a abertura do c\u00f3digo-fonte do framework Pingora, destinado ao desenvolvimento de servi\u00e7os de rede de alto desempenho e sistemas de rede program\u00e1veis usando a linguagem Rust. O framework foi bem testado e j\u00e1 est\u00e1 em uso em sistemas de alta carga \u2014 um proxy constru\u00eddo com base nele est\u00e1 em funcionamento na rede de entrega de conte\u00fado da Cloudflare h\u00e1 mais de um ano, processando mais de 40 milh\u00f5es de solicita\u00e7\u00f5es por segundo. O c\u00f3digo foi escrito na linguagem Rust e publicado sob a licen\u00e7a Apache 2.0. <\/p>\n

O Pingora pode ser usado para processamento de solicita\u00e7\u00f5es em multithreading de forma ass\u00edncrona, suporta HTTP\/1 e HTTP\/2 (com planos para HTTP\/3), proxy para gRPC e WebSocket, balanceadores de carga plug\u00e1veis, altera\u00e7\u00e3o de configura\u00e7\u00f5es sem rein\u00edcio, atualiza\u00e7\u00e3o de c\u00f3digo sem desconex\u00e3o, defini\u00e7\u00e3o de estrat\u00e9gias de failover e integra\u00e7\u00e3o com diversos sistemas de monitoramento e registro de logs (Syslog, Prometheus, Sentry, OpenTelemetry). O Pingora tamb\u00e9m suporta criptografia TLS, mas isso \u00e9 implementado como uma camada sobre as bibliotecas C OpenSSL e BoringSSL. <\/p>\n

Pacotes Rust prontos s\u00e3o fornecidos para criar proxies HTTP, trabalhar com protocolos de rede, analisar cabe\u00e7alhos HTTP, contabilizar e limitar tr\u00e1fego, balancear carga, trabalhar com a tabela hash distribu\u00edda Ketama, manter cache em mem\u00f3ria e processar limita\u00e7\u00f5es de tempo de forma ass\u00edncrona. Al\u00e9m do HTTP, suporta a cria\u00e7\u00e3o de servi\u00e7os que utilizam seus pr\u00f3prios protocolos ou UDP\/TCP. <\/p>\n

A seguran\u00e7a foi destacada como a prioridade principal do projeto \u2014 para reduzir a probabilidade de erros relacionados ao gerenciamento de mem\u00f3ria, a linguagem Rust foi escolhida para o desenvolvimento. A efici\u00eancia, o desempenho e a escalabilidade tamb\u00e9m receberam grande aten\u00e7\u00e3o. Por exemplo, ao criar o proxy -servidores<\/a> e no caso de balanceadores de carga baseados no Pingora, a possibilidade de anexar manipuladores de callback e filtros \u00e9 prevista, permitindo o gerenciamento de v\u00e1rias etapas do processamento de solicita\u00e7\u00f5es, al\u00e9m de modificar, redirecionar, bloquear e registrar solicita\u00e7\u00f5es e respostas. <\/p>\n

Juntamente com a organiza\u00e7\u00e3o ISRG (Internet Security Research Group), que \u00e9 a fundadora do projeto Let’s Encrypt e promove o desenvolvimento de tecnologias para aumentar a seguran\u00e7a na internet, ser\u00e1 criado um proxy reverso chamado River, baseado no Pingora, voltado para uso em elementos cr\u00edticos. da infraestrutura de rede<\/a>. O c\u00f3digo do River ser\u00e1 escrito em Rust e distribu\u00eddo sob a licen\u00e7a Apache 2.0. O desenvolvimento come\u00e7ar\u00e1 no segundo trimestre de 2024. Atualmente, o projeto est\u00e1 na fase de design e defini\u00e7\u00e3o da arquitetura. O projeto est\u00e1 sendo desenvolvido sob a lideran\u00e7a de James Munns do Rust Embedded Working Group. <\/p>\n

O principal objetivo do projeto River \u00e9 implementar um proxy capaz de retransmitir solicita\u00e7\u00f5es de clientes para servidores de backend, terminando conex\u00f5es TLS de entrada e roteando, alterando e filtrando solicita\u00e7\u00f5es de acordo com regras definidas. Entre as caracter\u00edsticas do River, destaca-se o modelo de processamento de solicita\u00e7\u00f5es multithread, que permite um uso mais eficiente da reutiliza\u00e7\u00e3o de conex\u00f5es em compara\u00e7\u00e3o com proxies como o nginx. Para expandir a funcionalidade do proxy e criar filtros, m\u00f3dulos compilados no formato WebAssembly ser\u00e3o suportados (qualquer linguagem de programa\u00e7\u00e3o que suporte compila\u00e7\u00e3o em WASM poder\u00e1 ser usada para o desenvolvimento). O formato da configura\u00e7\u00e3o est\u00e1 planejado para ser o mais simples e familiar poss\u00edvel.
