Cloud NGFW for AWS supports two primary deployment models:
A. Hierarchical: This is not a standard deployment model for Cloud NGFW for AWS. Hierarchical typically refers to a parent-child relationship in management, which isn't the core focus of the Cloud NGFW's deployment models.
B. Centralized: This is a VALID deployment model. In a centralized deployment, the Cloud NGFW is deployed in a central VPC (often a Transit Gateway VPC) and inspects traffic flowing between different VPCs and on-premises networks. This provides a single point of control for security policies.
[Reference: Palo Alto Networks documentation for Cloud NGFW on AWS explicitly describes the centralized deployment model., C. Distributed: This is a VALID deployment model. In a distributed deployment, the Cloud NGFW is deployed in each application VPC or segment, providing more granular security control and potentially lower latency for application traffic., Reference: Palo Alto Networks documentation for Cloud NGFW on AWS explicitly describes the distributed deployment model., D. Linear: This is not a standard deployment model term used for Cloud NGFW for AWS., , ]
