Auto scaling templates for VM-Series firewalls enable deployment of a single auto scaling group (ASG) of VM-Series firewalls to secure inbound traffic from the internet to Amazon Web Services (AWS) application workloads. An ASG is a collection of EC2 instances that share similar characteristics and can be scaled up or down automatically based on demand or predefined conditions. Auto scaling templates for VM-Series firewalls are preconfigured templates that provide the necessary resources and configuration to deploy and manage VM-Series firewalls in an ASG on AWS. Auto scaling templates for VM-Series firewalls can be used to secure inbound traffic from the internet to AWS application workloads by placing the ASG of VM-Series firewalls behind an AWS Application Load Balancer (ALB) or a Gateway Load Balancer (GWLB) that distributes the traffic across the firewalls. The firewalls can then inspect and enforce security policies on the inbound traffic before sending it to the application workloads. Auto scaling templates for HA-Series, CN-Series, and IPA-Series firewalls do not enable deployment of a single ASG of VM-Series firewalls to secure inbound traffic from the internet to AWS application workloads, as those are different types of firewalls that have different deployment models and use cases.

Dynamic Address Group is the PAN-OS feature that allows for automated updates to address objects when VM-Series firewalls are setup as part of an NSX deployment. NSX is a software-defined network (SDN) solution that provides network virtualization, automation, and security for cloud-native applications. Dynamic Address Group is an object that represents a group of IP addresses based on criteria such as tags, regions, interfaces, or user-defined attributes. Dynamic Address Group allows Security policies to adapt dynamically to changes in the network topology or workload characteristics without requiring manual updates. When VM-Series firewalls are setup as part of an NSX deployment, they can leverage the NSX tags assigned to virtual machines (VMs) or containers by the NSX manager or controller to populate Dynamic Address Groups and update Security policies accordingly. Boundary automation, Hypervisor integration, and Bootstrapping are not PAN-OS features that allow for automated updates to address objects when VM-Series firewalls are setup as part of an NSX deployment, but they are related concepts that can be used for other purposes.

Cloud next-generation firewall is the Palo Alto Networks software firewall that protects Amazon Web Services (AWS) deployments with network security delivered as a managed cloud service. Cloud next-generation firewall is a cloud-native solution that provides comprehensive security and visibility across AWS environments, including VPCs, regions, accounts, and workloads. Cloud next-generation firewall is deployed and managed by Palo Alto Networks as a service, eliminating the need for customers to provision, configure, or maintain any infrastructure or software. VM-Series, CN-Series, and Ion-Series are not Palo Alto Networks software firewalls that protect AWS deployments with network security delivered as a managed cloud service, but they are related solutions that can be deployed on AWS or other platforms.

The number of required flex credits for a VM-Series firewall depends on vCPU allocation. Flex credits are a flexible licensing model that allows customers to purchase and consume software NGFWs as needed, without having to specify the platform or deployment model upfront. Customers can use flex credits to provision VM-Series firewalls on any supported cloud or virtualization platform. The number of required flex credits for a VM-Series firewall depends on vCPU allocation, which is the number of virtual CPUs assigned to the VM-Series firewall instance. The vCPU allocation determines the performance and capacity of the VM-Series firewall instance, such as throughput, sessions, policies, rules, and features. The number of required flex credits for a VM-Series firewall does not depend on IP address allocation, network interface allocation, or memory allocation, as those are not factors that affect the licensing cost or consumption of flex credits.

The two features of CN-Series firewalls that protect east-west traffic between pods in different trust zones are:

Intrusion prevention system

Layer 7 visibility

East-west traffic is the traffic that flows between applications or workloads within a network or a cloud environment. Pods are the smallest units of deployment in Kubernetes, consisting of one or more containers that share resources and network space. Trust zones are segments of the network or the cloud environment that have different levels of security requirements or policies based on data sensitivity, user identity, device type, or application function. CN-Series firewalls are containerized firewalls that integrate with Kubernetes and provide visibility and control over container traffic. Intrusion prevention system is a feature of CN-Series firewalls that protects east-west traffic between pods in different trust zones by detecting and blocking known exploits and vulnerabilities using signature-based and behavior-based methods. Layer 7 visibility is a feature of CN-Series firewalls that protects east-west traffic between pods in different trust zones by identifying and classifying applications and protocols based on their content and characteristics, regardless of port, encryption, or evasion techniques. Communication with Panorama and external load balancer are not features of CN-Series firewalls that protect east-west traffic between pods in different trust zones, but they are related features that can enhance management and performance.
