This page shows that you are also charged if you remap them too often (more then 100 times a month), this I didn't realize: https://aws.amazon.com/ec2/pricing/on-demand/#Elastic_IP_Addresses are limited in resources (we have a lot of VMs) and cause a lot of > headaches in our autoscaling / infrastructure as code systems. > But you are not trying to autoscale Cassandra, do you? Cloud Formation has a decent support of EIPs, e.g. you can allocate them by declaring in resources and then resolve the address to inject configuration parameters for the application if needed. > We are probably going to just have a VM startup script for now that automatically updates the yaml on instance restart. It seems to be the least-sucky approach at this point. This is what we do for our docker-based setup. I think we were just following the documentation, though you're looking at the code proves that this shouldn't be required.. Regards, -- Alex
