In this session, you learn why Twilio chose to migrate from Amazon EC2-Classic to VPC and how they leveraged features available only in VPC, specifically:

- AWS CloudHSM: Build out a secure key encryption or role-based access control for internal use; also used to securely store and encrypt data for external customers.- Elastic Network Interface (ENI): Allows multiple Elastic IPs per instance and the ability to move network interface between instances.- Hardware Virtual Machine (HVM) instances w/SRV-IO: New hardware virtualized instances that allow line-level performance of network interfaces for up to 10g Ethernet speeds. Secure data-in-transit by default, which ensures all machines communicate via a software-defined network and work in the same manner as VLAN tagging for compliance reasons. Sponsored by Twilio.
