-A host group is a resource that represents a collection of dedicated hosts. You create a host group in a region and an availability zone, and add hosts to it. When planning for high availability, there are more options. You can use one or both of the following options with your dedicated hosts:
-
-* Span across multiple availability zones. In this case, you're required to have a host group in each of the zones you wish to use.
-* Span across multiple fault domains, which are mapped to physical racks.
-
-In either case, you need to provide the fault domain count for your host group. If you don't want to span fault domains in your group, use a fault domain count of 1.

-You can also decide to use both availability zones and fault domains.

 Not all host SKUs are available in all regions, and availability zones. You can list host availability, and any offer restrictions before you start provisioning dedicated hosts.

 ## Create a Host Group
 
 Now create a dedicated host in the host group. In addition to a name for the host, you're required to provide the SKU for the host. Host SKU captures the supported VM series and the hardware generation for your dedicated host.
