As already mentioned, ElastiCache nodes in a cluster only have private IP addresses. Therefore, you can’t connect to a node directly over the internet. The same is true for other resources as EC2 instances or RDS instances. To test the Redis cluster, you can create an EC2 instance in the same VPC as the cluster. From the EC2 instance, you can then connect to the private IP address of the cluster.

Once the stack status changes to CREATE_COMPLETE in the CloudWatch Management Console, select the stack and click on the Outputs tab. You can now start to test the Redis cluster. Open an SSH connection to the EC2 instance, and then you can use the Redis CLI to interact with the Redis cluster node.
