Добрый день!
Решил тут затестить самый дешевый тариф VPS от Ihor за 100 рублей в месяц. За эти деньги нам доступна виртуальная машина с 512 мегабайтами оперативной памяти, 1 ядром и 10 гигабайтами HDD.
Процесс заказа

Есть большой выбор ОС.

Можно докупить панель управления и ip-адреса

Выводы
Сервер радует низкой ценой, но вот с HDD живется не очень хорошо. Я бы посоветовал взять более дорогой тариф за 150 рублей c SSD. Думаю подойдет для каких-либо нетребовательных по ресурсам систем которые по какой-то причине нет возможности запустить на шаред-хостинге. Также радует что виртуалка расположена в Москве (ДЦ Мароснет) и находится под защитой от DDoS.
