Bare metal servers and dedicated hosts are physically-isolated servers dedicated to individual tenants. Their differences are as follows:
- DeH: A dedicated host is fully exclusive for your ECSs, but cannot be directly used for running workloads. You can deploy ECSs for running workloads on a dedicated host.
- BMS: A BMS is used as a physical server and can be directly used for running your services.
