## Example

```ts
declare const vpc: ec2.Vpc;

const expressCluster = new msk.Cluster(this, 'ExpressCluster', {
  clusterName: 'MyExpressCluster',
  kafkaVersion: msk.KafkaVersion.V3_8_X,
  vpc,

| `STANDARD` | Standard brokers provide high-availability guarantees. |
| `EXPRESS` | Express brokers are a low-cost option for development, testing, and workloads that don't require the high availability guarantees of standard MSK cluster. |
