If you enable automatic deployment for a dedicated host, the dedicated host is added to the resource pool of your Alibaba Cloud account for automatic deployment. When you create an Elastic Compute Service (ECS) instance, you do not need to specify a dedicated host. The system selects a dedicated host from the resource pool to deploy the instance. This improves deployment flexibility.
