С помощью nginx/angie и встроенного модуля perl можно проксировать запросы напрямую к S3. Ниже приведён пример для реализации S3 от DigitalOcean (Spaces). Для Amazon AWS S3 пример тоже подходит. Для авторизации доступа можно использовать пример совместно с модулем [[http://nginx.org/ru/docs/http/ngx_http_secure_link_module.html secure_link]].

    'sub {
        use POSIX qw(strftime);
        return strftime("%Y%m%dT%H%M%SZ", gmtime());
    }';
