Доброй ночи!
Очень давно сюда не писал, а ведь получил промокод на тестирование новых виртуалок с NVME-дисками еще на конференции “Стачка” в апреле 2018 года. Тогда же я все и затестил, а потом просто забыл все опубликовать =) Теперь вот исправляю оплошность.
Панель управления
Тут все просто, нас встречает VMmanager в котором можно создавать инстансы и выбирать ОС из шаблонов или предустановленные окружения (Битрикс, Django и т.д.).


Выбранная мной машина стоит 379 рублей в месяц. За эту сумму нам дают 1 ядро, 1 гигабайт ОЗУ и 20 гигабайт NVME-диска на KVM. На нее я традиционно поставил CentOS.
