We currently have a web application running exclusively on AWS. The current configuration consists of a single EC2 Windows Server 2012 instance with an AWS RDS MySQL database backend. We are in need of assistance in planning and deploying a secure VPC in AWS for remote networks to securely send data over the VPC IPSec tunnel. The remote networks will primarily consist of Cisco, Juniper, Checkpoint, etc. hardware. We have no control over these third-party networks and will be required to provide detailed configuration instructions to setup the AWS VPC / VPN connection to the third-parties. This project could eventually scale out to thousands of networks and thus a well-thought out network design plan is a must.
