# AWS::SageMaker::EndpointConfig ServerlessConfig
<a name="aws-properties-sagemaker-endpointconfig-serverlessconfig"></a>

Specifies the serverless configuration for an endpoint variant.

## Syntax
<a name="aws-properties-sagemaker-endpointconfig-serverlessconfig-syntax"></a>

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

### JSON
<a name="aws-properties-sagemaker-endpointconfig-serverlessconfig-syntax.json"></a>

```
{
  "[MaxConcurrency](#cfn-sagemaker-endpointconfig-serverlessconfig-maxconcurrency)" : Integer,
  "[MemorySizeInMB](#cfn-sagemaker-endpointconfig-serverlessconfig-memorysizeinmb)" : Integer,
  "[ProvisionedConcurrency](#cfn-sagemaker-endpointconfig-serverlessconfig-provisionedconcurrency)" : Integer
}
```

### YAML
<a name="aws-properties-sagemaker-endpointconfig-serverlessconfig-syntax.yaml"></a>

```
  [MaxConcurrency](#cfn-sagemaker-endpointconfig-serverlessconfig-maxconcurrency): Integer
  [MemorySizeInMB](#cfn-sagemaker-endpointconfig-serverlessconfig-memorysizeinmb): Integer
  [ProvisionedConcurrency](#cfn-sagemaker-endpointconfig-serverlessconfig-provisionedconcurrency): Integer
```
