Cloud NGFW for AWS Distributed Deployments
Cloud NGFW for AWS distributed deployments.
Where Can I Use This? What Do I Need?
Cloud NGFW subscription Palo Alto Networks Customer Support Account (CSP) AWS Marketplace account User role (either tenant or administrator)
In a distributed deployment, each VPC that requires protection has its own NGFW. This
deployment method is less complicated and, therefore, reduces the chance of
misconfiguration.
Distributed East-West (intra-VPC)
Traffic from the source instance is routed to the NGFW endpoint and on to the
NGFW for inspection.
If the traffic is allowed, the NGFW endpoint sends the traffic on to the
destination.
Distributed Outbound
Traffic from the source instance is routed to the NGFW endpoint and on to the
NGFW for inspection.
If the traffic is allowed, the NGFW endpoint sends the inspected traffic to
the NAT gateway.
The NAT gateway sends the traffic to the internet gateway.
The traffic continues to the internet and the destination.
Distributed Inbound
Traffic from the source arrives at the internet gateway.
The internet gateway routes the traffic to the NGFW endpoint and then to the
NGFW for inspection.
If the traffic is allowed, the NGFW endpoint routes the traffic to the
application load balancer.
The application load balancer forwards the traffic to the destination.
