Dedicated Host (DDH) is a host service that allows a tenant to use dedicated hardware resources based on Alibaba Cloud virtual hosting services. This service enables enterprises to achieve custom deployment, bring your own license (BYOL), and security and regulation compliance. DDH supports multiple types of ECS instances. ECS instances created on a DDH feature the same performance and stability as other ECS instances created in the cloud.
- Security and Regulation Compliance
Allows you to allocate dedicated hardware resources, such as CPU, memory, and network resources, to isolate physical servers for sensitive business data.
Allows you to use your own licenses to create ECS instances. This reduces the investment on cloud deployment.
- Custom Deployment
Allows you to create ECS instances on the specified DDH and migrate ECS instances between a DDH environment and a multi-tenant environment.
- Same Features as ECS
ECS instances created on a DDH run stably and possess the same compute, network, and storage features as ECS.
