 ** InstanceCount **   <a name="sagemaker-Type-ProcessingInstancePreference-InstanceCount"></a>
The number of instances to launch if this instance type is selected. Specify the instance count for the processing job in one of the following two ways:  

1.  **Per preference** – Set `InstanceCount` on every preference in the `InstancePreferences` list and don't set `ProcessingClusterConfig$InstanceCount`. Use this when each instance type needs a different number of instances to deliver equivalent compute.

1.  **One count for the job** – Set `ProcessingClusterConfig$InstanceCount` and omit it from every preference. Amazon SageMaker applies this to all instance types in the list.
For example, in a list of five preferences, either all five specify `InstanceCount` or none of them do. Amazon SageMaker rejects requests that set `InstanceCount` on only some preferences, that set it both per preference and in `ProcessingClusterConfig`, or that omit it in both places.  
Type: Integer  
Valid Range: Minimum value of 1. Maximum value of 100.
