What Are the Differences Between BMS and Dedicated Host (DeH)?

Both BMS and DeH allow you to exclusively use physical servers but they have the following differences:

BMS uses the bare metal architecture and does not provide a virtualization platform by default. You need to install virtualization software on a BMS before you provision an ECS on it.
DeH provides a virtualization platform by default. After purchasing a DeH, you can directly provision ECSs on it.

For more information, see Table 1.
