Протестировал московский IaaS ориентированный на клиентов предъявляющих серьезные требования к качеству и надежности. Виртуализация здесь VMware. Фиксированных тарифов нет - в онлайн калькуляторе можно накрутить подходящий по цене и производительности сервер. Есть даже возможность докупить ip по 40 рублей за штуку. Для теста мне предоставили вот такую машинку:
1 ядро Xeon E5 2690v2 512 мб памяти 10 гб SSD диск 300 Мбит интернет 1 IP
Стоимость 922,5 руб. в месяц. Без оверсела, без лимитов по нагрузке на проц и память.
Под катом небольшие результаты тестов
Смотрим что нам досталось на тест:
Пинги до Москвы из Ульяновска закономерно очень короткие. Всего 27мс.

Вывод: В синтетических тестах сервер показал довольно высокую производительность. Плюс он находится в Москве, а значит для клиентов из России доступ будет быстрее. Отличная надежная машина минус которой разве что в высокой цене. Но оно того стоит.
