v85 v86 274 274 1) Resources allocated on the Amazon EC2 cloud have to be connected with other GENI resources to participate in an experiment. Disk resources (S3 or EBS) can only be accessed from EC2 servers called instances. 275 275 276 2) EC2 instances (servers) are dynamically assigned IP addresses when they are created. A public IP address is available for remote connections and a private IP address is created for internal communications (inside EC2). All network traffic between EC2 instances (inside the same availability zone of the same region) is free. Traffic between resources in different regions is considered Internet traffic. All network exchanges between GENI 277 resources outside of EC2 and EC2 resources are charged. 276 2) EC2 instances (servers) are dynamically assigned IP addresses when they are created.

A customer is limited to 5 such addresses by default but more can be obtained on demand.
