Cloud WAN “actually builds it for you in minutes using the big AWS backbone for you, to give you a highly reliable, highly available, software-defined wide area network running over AWS infrastructure,” Vogels said.

These segments would not be able to communicate with each other unless explicitly allowed. The service includes a dashboard for monitoring network health, security, and performance.
