Stopping the AWS Instances (Optional)
Once you have removed one or more nodes from your cluster, to save costs associated with running instances, you can choose to stop or terminate the AWS instances that were previously part of your cluster. This step is optional because, once you have removed the node from your Vertica cluster, Vertica no longer sees the instance/node as part of the cluster even though it is still running within AWS.
To stop an instance in AWS:
- On AWS, navigate to your Instances page.
- Right-click on the instance, and choose Stop.
