US Patent 11868448 Shared dedicated host resource groups in a provider network

Techniques for host resource group sharing in a provider network are described. A resource share is made of a host resource group made up of dedicated hosts in the provider network. The share provides access to the host resource group of a primary account with one or more other principals—e.g., user accounts, an organization, or a group of users. The other principals can launch compute instances into the host resource group, which may cause the automatic provisioning of new hosts into the host resource group, of the primary account, as needed.
