# AWS::SageMaker::DeviceFleet
<a name="aws-resource-sagemaker-devicefleet"></a>

The `AWS::SageMaker::DeviceFleet` resource is an Amazon SageMaker resource type that allows you to create a DeviceFleet that manages your SageMaker Edge Manager Devices. You must register your devices against the `DeviceFleet` separately.

## Syntax
<a name="aws-resource-sagemaker-devicefleet-syntax"></a>

To declare this entity in your CloudFormation template, use the following syntax:
