# AWS::Lambda::CapacityProvider CapacityProviderScalingConfig
<a name="aws-properties-lambda-capacityprovider-capacityproviderscalingconfig"></a>

Configuration that defines how the capacity provider scales compute instances based on demand and policies.

## Syntax
<a name="aws-properties-lambda-capacityprovider-capacityproviderscalingconfig-syntax"></a>

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

### JSON
<a name="aws-properties-lambda-capacityprovider-capacityproviderscalingconfig-syntax.json"></a>

```
{
  "[MaxVCpuCount](#cfn-lambda-capacityprovider-capacityproviderscalingconfig-maxvcpucount)" : Integer,
  "[ScalingMode](#cfn-lambda-capacityprovider-capacityproviderscalingconfig-scalingmode)" : String,
  "[ScalingPolicies](#cfn-lambda-capacityprovider-capacityproviderscalingconfig-scalingpolicies)" : [ TargetTrackingScalingPolicy, ... ]
}
```

### YAML
<a name="aws-properties-lambda-capacityprovider-capacityproviderscalingconfig-syntax.yaml"></a>

```
  [MaxVCpuCount](#cfn-lambda-capacityprovider-capacityproviderscalingconfig-maxvcpucount): Integer
  [ScalingMode](#cfn-lambda-capacityprovider-capacityproviderscalingconfig-scalingmode): String
  [ScalingPolicies](#cfn-lambda-capacityprovider-capacityproviderscalingconfig-scalingpolicies): 
    - TargetTrackingScalingPolicy
```

## Properties
<a name="aws-properties-lambda-capacityprovider-capacityproviderscalingconfig-properties"></a>

`MaxVCpuCount`  <a name="cfn-lambda-capacityprovider-capacityproviderscalingconfig-maxvcpucount"></a>

*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ScalingMode`  <a name="cfn-lambda-capacityprovider-capacityproviderscalingconfig-scalingmode"></a>
The scaling mode that determines how the capacity provider responds to changes in demand.  
*Required*: No  
*Type*: String  
*Allowed values*: `Auto | Manual`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)

`ScalingPolicies`  <a name="cfn-lambda-capacityprovider-capacityproviderscalingconfig-scalingpolicies"></a>
A list of target tracking scaling policies for the capacity provider.  
*Required*: No  
*Type*: Array of [TargetTrackingScalingPolicy](aws-properties-lambda-capacityprovider-targettrackingscalingpolicy.md)  
*Minimum*: `1`  
*Maximum*: `10`  
*Update requires*: [No interruption](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
