# InstanceType

Possible Instances Types to use in Neptune cluster used for defining `DatabaseInstanceProps.instanceType`.

- Stability: [Experimental](/cdk/api/stability.html)
- Source: [`lib/instance.ts`](https://github.com/aws/aws-cdk/blob/v2.275.0-alpha.0/packages/@aws-cdk/aws-neptune-alpha/lib/instance.ts#L17)

## Example

```ts
const cluster = new neptune.DatabaseCluster(this, 'ServerlessDatabase', {
  vpc,
  instanceType: neptune.InstanceType.SERVERLESS,
  serverlessScalingConfiguration: {
    minCapacity: 1,
    maxCapacity: 5,
  },
});
```
