A DDH is a cloud host with physical resources that are used exclusively by a single tenant. After you create a DDH, you gain exclusive access to all of its physical resources.
Create an ECS instance on a DDH
You can create ECS instances on a DDH and then deploy your services on the instances. This provides a dedicated physical server and exclusive access to physical resources, such as CPUs, memory, and network interface controllers (NICs), for improved security.
