# InferenceComponentCapacitySize
<a name="API_InferenceComponentCapacitySize"></a>

Specifies the type and size of the endpoint capacity to activate for a rolling deployment or a rollback strategy. You can specify your batches as either of the following:
+ A count of inference component copies 
+ The overall percentage or your fleet 

For a rollback strategy, if you don't specify the fields in this object, or if you set the `Value` parameter to 100%, then SageMaker AI uses a blue/green rollback strategy and rolls all traffic back to the blue fleet.
