Application and landing zone components

The sample web application deployment described in this section consists of the following:

1. Ubuntu server with NGINX web server hosted on an EC2 instance in a private subnet

2. Network load balancer is deployed in a protected subnet and exposes the web server to the Internet

3. AWS firewall is deployed in the public subnet and inspects all ingress and egress traffic. the firewall rules allow only web server related traffic to the Internet (80, 443) and allows ssh connections to the web server initiated internally within the VPC

The following diagram depicts the landing zone that is used in this sample deployment:
