Добрый день!
Решил тут затестить самый дешевый тариф VPS от VDS за 249 рублей в месяц. За эти деньги нам доступна виртуальная машина с 1 гигабайтом оперативной памяти, 1 ядром и 30 гигабайтами SSD. Ограничение по трафику - 2Тб в месяц.
Панель управления
Есть возможность заказа VDS в двух ДЦ в Москве и Амстердаме. Также есть возможность заказа VDS с Windows.
Можно добавить свой SSH-ключ
Можно загрузить свой ISO
Есть возможность купить свой SSL
Есть возможность использования DNS хостера
Общая информация по аккаунту. Есть лимиты
Можно ограничить доступ к аккаунту по ip
Можно создавать дополнительных пользователей
И гибко настраивать им права
Заказанная тестовая VDS
Настройки VDS
Есть возможность подключения к виртуалке по VNC
Есть возможность докупить IP
Есть возможность создавать снапшоты
Можно смотреть статистику по использованию ресурсов на VDS
