About this Hands-on Lab

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.

Our task is configure the application server so that it connects to both the public and private subnets, and obtains an IP address on each one. The VPC is using a Class C CIDR of The public subnet is using the CIDR, and the private subnet is using the CIDR

Being consultants, we know things don't always go as planned. We need to assess the environment, take corrective action as necessary, and complete the task of dual-homing the instance.
