Configure an Amazon EC2 Instance with Dual-Homed Network Connectivity
In this Hands-On Lab we are assuming the role of AWS consultants who have been tasked with configuring an Amazon EC2 instance to support a new application. The application requires connection to two different networks, so the application server must be connected to two different subnets.
The first is public subnet, for public access to the web application. The second is where a custom database server resides. The database is a customized application, and requires the application server to have an IP address on the same subnet.
