 ** InstanceTypes **   <a name="sagemaker-Type-ClusterInstanceRequirements-InstanceTypes"></a>
The list of instance types that the instance group can use. The order of instance types determines the priority—HyperPod attempts to provision instances using the first instance type in the list and falls back to subsequent types if capacity is unavailable.  
Type: Array of strings  
Array Members: Minimum number of 1 item. Maximum number of 20 items.
