The process for creating a cucloud.net Hosted Zone in your AWS account and requesting DNS delegation can be found in Route 53 Subdomain Delegation.
How can confirm that a peering connection is being used for 10-space traffic instead of the Direct Connect.
Suppose I have two AWS VPCs that are both connected to campus networks with Direct Connect. How can I tell if traffic between those two VPCs are using an AWS peering connection or traveling the Direct Connect and making a u-turn on-campus? The answer is to look at the results of traceroute
between two IPs, one in each VPC.
Here is the traffic pattern traceroute
would return when Direct Connect is being used

Working with Data
When should I use Direct Connect and when should I use the public internet to transfer data?
