Доброй ночи!
Затестил тут на днях сервер от Vscale за 200 рублей. За эти деньги нам дают в распоряжение машинку на 512 мегабайт памяти, с одним ядром процессора и 20Gb SSD. Локации две на выбор - Москва и Санкт-Петербург.
Вообще сервис очень сильно похож на DigitalOcean и Vultr как по дизайну так и по возможностям с ценами. Цены я бы не сказал что низкие, так по цене мощных виртуалок можно взять и полноценные дедики в разы более мощные и за ту же цену.
Но тут дело немного в другом - сервис позиционируется для разработчиков. То есть предполагается что инстансы будут постоянно создаваться и уничтожаться по мере надобности. Для того чтобы делать это не вручную есть даже удобный API. И в конечном счете тут можно выгодно приобретать необходимые серверные мощности на непродолжительное время.
Итак, перейдем к тесту. Я поднял виртуалку в локации Москва.
