Re: How do you do automatic restacking of AWS instance for cassandra?

I understand that, but I'm not sure your point. If you used ebs, you could stop one instance at a time, swap out your OS drive via new AMI, and start it again attached to your existing data drive, and bounce a whole cluster in a rolling manner, perhaps 5 minutes per node. If you don't want to
