In this use case, we show you how to secure highly available two-tier applications in Amazon Web Services (AWS) that are accessed by users over the internet. This setup is one specific example that uses WordPress and MySQL as the 2-tier applications. It includes a relational database service, a DNS-based global load balancing web service, Citrix NetScaler load balancers, and several VM-Series firewalls to secure north-south and east-west traffic flows to the applications in the Amazon Virtual Private Cloud (VPC). For high availability, the VPC spans two Availability Zones (AZs) in AWS. There are many other applications and architectures that Palo Alto Networks firewalls can secure; this use case is just one option.
