Vultr.com is relatively “new” player in the cloud hosting market but with very great vps service level they have provided and with very cheap price vps level they have offered for the specs, they will soon become one of the best vps hosting providers.
Overall, if you looking DigitalOcean alternative, Vultr.com is the right choice.
