Cassandra on Amazon EC2 with Elastic IP addresses

Question

Can I used cassandra on EC2 instances without Elastic IP addresses? I believe in that case any instance that goes down, would create an issue.

If I use Elastic IP addresses for the cassandra nodes, I have to configure them such that they use the Public IP address for internal communication (gossip etc.). But that will increase the network latency.

Please suggest how should I configure my nodes such that the problems can be minimized.

Answer 1

My answer would be, use Rackspace Cloud Servers instead because you get better i/o performance as well as both public and internal IPs.

But there are several people in the community using EC2; I'd ask on the cassandra-user list if you insist on that. :)
