> There are no current replication strategies to deal with different data centers in an
EC2 cluster. The IP address comparisons used in the current implementations aren't enough
to guarantee that an endpoint is in the same datacenter.  By supplying the access and secret
key to a client's AWS account, Cassandra should use the amazon-ec2 java library to access
information about each endpoint.
