# AWS::Amplify::App JobConfig
<a name="aws-properties-amplify-app-jobconfig"></a>

Describes the configuration details that apply to the jobs for an Amplify app.

Use `JobConfig` to apply configuration to jobs, such as customizing the build instance size when you create or update an Amplify app. For more information about customizable build instances, see [Custom build instances](https://docs.amazonaws.cn/amplify/latest/userguide/custom-build-instance.html) in the *Amplify User Guide*.

## Syntax
<a name="aws-properties-amplify-app-jobconfig-syntax"></a>

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

### JSON
<a name="aws-properties-amplify-app-jobconfig-syntax.json"></a>

```
{
  "[BuildComputeType](#cfn-amplify-app-jobconfig-buildcomputetype)" : {{String}}
}
```

### YAML
<a name="aws-properties-amplify-app-jobconfig-syntax.yaml"></a>

```
  [BuildComputeType](#cfn-amplify-app-jobconfig-buildcomputetype): {{String}}
```

## Properties
<a name="aws-properties-amplify-app-jobconfig-properties"></a>

`BuildComputeType`  <a name="cfn-amplify-app-jobconfig-buildcomputetype"></a>
Specifies the size of the build instance. Amplify supports three instance sizes: `STANDARD_8GB`, `LARGE_16GB`, and `XLARGE_72GB`. If you don't specify a value, Amplify uses the `STANDARD_8GB` default.  
The following list describes the CPU, memory, and storage capacity for each build instance type:    
STANDARD\_8GB  
+ vCPUs: 4
+ Memory: 8 GiB
+ Disk space: 128 GB  
LARGE\_16GB  
+ vCPUs: 8
+ Memory: 16 GiB
+ Disk space: 128 GB  
XLARGE\_72GB  
+ vCPUs: 36
+ Memory: 72 GiB
+ Disk space: 256 GB
*Required*: Yes  
*Type*: String  
*Allowed values*: `STANDARD_8GB | LARGE_16GB | XLARGE_72GB`  
*Update requires*: [No interruption](https://docs.amazonaws.cn/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-no-interrupt)
