In order to distribute Elasticache cluster nodes among several AWS Availability Zones, follow these steps:

1. Create a new Elasticache cluster or select an existing one.
2. Click on the "Modify" button to edit the cluster configuration.
3. Under the "Multi-AZ" section, select the option to enable multi-AZ deployment.
4. Specify the number of replica nodes per primary node that you want to use.
5. Choose the AWS Availability Zones where you want to deploy the nodes.
6. Click on the "Apply Immediately" button to save the changes.

After you have completed these steps, Elasticache will automatically distribute your cluster nodes across the selected AWS Availability Zones to ensure high availability and fault tolerance. It is recommended to choose at least two Availability Zones for multi-AZ deployment.
