You will need to have the nodes running on AWS in a VPC. You can then configure a VPN to work with your VPC, see http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_VPN.html. Also as you will have multiple VPN connections (from your private DC and the other AWS region) AWS CloudHub will be the way to go http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPN_CloudHub.html.
Additionally to access your Cassandra instances from your other VPCs you can use VPC peering (within the same region).
