DigitalOcean only provides VPS’s (Droplets), however, a VPS functions much like a Dedicated Server in many ways.
You’re able to choose your OS during deployment and you’ll receive root access which allows you to configure the VPS to your liking.
VPS’s are deployed using KVM, which is virtualization, however, the RAM that is allocated to your VPS is dedicated in a sense that no other VPS will be able to use it. You’re able to fully utilize 100%. There’s no burstable RAM (as there would be on an OpenVZ or similar VPS), so the RAM you see is the RAM you’ll receive.
CPU Cores are shared, though your Droplet gets it’s own share; whether that’s 1, 2, 4, 8, 12, 16 or 20 CPU Cores depends on the Droplet size you choose.
