A empresa Intel anunciou o encerramento do projeto Clear Linux, que desenvolvia uma distribui\u00e7\u00e3o com estrita isola\u00e7\u00e3o de aplica\u00e7\u00f5es, implementada atrav\u00e9s de cont\u00eaineres separados utilizando virtualiza\u00e7\u00e3o completa. A partir de hoje, a Intel cessar\u00e1 o suporte e n\u00e3o lan\u00e7ar\u00e1 mais atualiza\u00e7\u00f5es e corre\u00e7\u00f5es de vulnerabilidades. Os reposit\u00f3rios do GitHub, onde o desenvolvimento da distribui\u00e7\u00e3o ocorria, ser\u00e3o em breve transferidos para o modo de arquivo. <\/p>\n
Os usu\u00e1rios do Clear Linux s\u00e3o recomendados a migrar seus sistemas para outras distribui\u00e7\u00f5es. Cabe ressaltar que a Intel continuar\u00e1 a apoiar ativamente o ecossistema Linux e a participar do desenvolvimento de v\u00e1rios projetos abertos e distribui\u00e7\u00f5es Linux para adicionar suporte ao seu hardware e otimizar seu funcionamento. Acredita-se que os funcion\u00e1rios da Intel envolvidos no desenvolvimento do Clear Linux estar\u00e3o entre os que sofrer\u00e3o demiss\u00f5es em massa, com a empresa reduzindo seu quadro de pessoal em 5 mil pessoas. <\/p>\n
Vale lembrar que a parte b\u00e1sica do Clear Linux cont\u00e9m apenas um conjunto m\u00ednimo de ferramentas para executar cont\u00eaineres e \u00e9 atualizada de forma at\u00f4mica atrav\u00e9s da substitui\u00e7\u00e3o de instant\u00e2neas do Btrfs. Todos os aplicativos s\u00e3o formatados como pacotes Flatpak ou conjuntos (Bundle), executados em cont\u00eaineres separados. Dentro dos cont\u00eaineres, \u00e9 executada uma c\u00f3pia especificamente otimizada do Clear Linux, contendo os conjuntos necess\u00e1rios para executar o aplicativo de destino. <\/p>\n
A vers\u00e3o da distribui\u00e7\u00e3o abrange o estado das vers\u00f5es de todos os componentes inclu\u00eddos \u2014 qualquer altera\u00e7\u00e3o em uma parte do sistema resulta em uma altera\u00e7\u00e3o na vers\u00e3o total da distribui\u00e7\u00e3o. O sistema n\u00e3o mant\u00e9m seu estado (stateless) e, ap\u00f3s a instala\u00e7\u00e3o, n\u00e3o cont\u00e9m configura\u00e7\u00f5es pr\u00e9-adicionadas no diret\u00f3rio \/etc, mas gera configura\u00e7\u00f5es dinamicamente com base em templates fornecidos durante a inicializa\u00e7\u00e3o. <\/p>\n
Para a isola\u00e7\u00e3o dos cont\u00eaineres, \u00e9 utilizado o conjunto de ferramentas Kata Containers, que aplica virtualiza\u00e7\u00e3o completa baseada em hipervisor. KVM<\/a>. O Kata Containers conseguiu minimizar o tempo de inicializa\u00e7\u00e3o de um ambiente isolado baseado em KVM e reduzir o consumo de mem\u00f3ria, aproximando esses valores das caracter\u00edsticas de cont\u00eaineres comuns. Para diminuir o consumo de mem\u00f3ria, \u00e9 utilizado o mecanismo DAX (acesso direto ao sistema de arquivos, contornando o cache de p\u00e1ginas sem a utiliza\u00e7\u00e3o de um n\u00edvel de dispositivos de bloco), e para a deduplica\u00e7\u00e3o de \u00e1reas de mem\u00f3ria iguais, \u00e9 aplicada a tecnologia KSM (Kernel Shared Memory). \u041a\u043e\u043c\u043f\u0430\u043d\u0438\u044f Intel \u043e\u0431\u044a\u044f\u0432\u0438\u043b\u0430 \u043e \u0441\u0432\u043e\u0440\u0430\u0447\u0438\u0432\u0430\u043d\u0438\u0438 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 Clear Linux, \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u044e\u0449\u0435\u0433\u043e \u0434\u0438\u0441\u0442\u0440\u0438\u0431\u0443\u0442\u0438\u0432 \u0441\u043e \u0441\u0442\u0440\u043e\u0433\u043e\u0439 \u0438\u0437\u043e\u043b\u044f\u0446\u0438\u0435\u0439 \u043f\u0440\u0438\u043b\u043e\u0436\u0435\u043d\u0438\u0439, \u0440\u0435\u0430\u043b\u0438\u0437\u043e\u0432\u0430\u043d\u043d\u043e\u0439 \u043f\u0440\u0438 \u043f\u043e\u043c\u043e\u0449\u0438 \u043a\u043e\u043d\u0442\u0435\u0439\u043d\u0435\u0440\u043e\u0432, \u0440\u0430\u0437\u0434\u0435\u043b\u0451\u043d\u043d\u044b\u0445 \u0441 \u0438\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u0435\u043c \u043f\u043e\u043b\u043d\u043e\u0446\u0435\u043d\u043d\u043e\u0439 \u0432\u0438\u0440\u0442\u0443\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438. \u041d\u0430\u0447\u0438\u043d\u0430\u044f \u0441 \u0441\u0435\u0433\u043e\u0434\u043d\u044f\u0448\u043d\u0435\u0433\u043e \u0434\u043d\u044f Intel \u043f\u0440\u0435\u043a\u0440\u0430\u0449\u0430\u0435\u0442 \u0441\u043e\u043f\u0440\u043e\u0432\u043e\u0436\u0434\u0435\u043d\u0438\u0435 \u0438 \u0431\u043e\u043b\u044c\u0448\u0435 \u043d\u0435 \u0431\u0443\u0434\u0435\u0442 \u0432\u044b\u043f\u0443\u0441\u043a\u0430\u0442\u044c \u043e\u0431\u043d\u043e\u0432\u043b\u0435\u043d\u0438\u044f \u0438 \u0438\u0441\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u0438\u044f \u0441 \u0443\u0441\u0442\u0440\u0430\u043d\u0435\u043d\u0438\u0435\u043c \u0443\u044f\u0437\u0432\u0438\u043c\u043e\u0441\u0442\u0435\u0439.
