Service Cluster Mode:
In NSX-T, the Service Cluster mode allows the VM-Series firewalls to be deployed as part of a service
cluster, where they can provide security services to workloads.
Reference: The deployment guide for VM-Series firewalls in NSX-T outlines how to set up and configure
Service Cluster mode.
Palo Alto Networks NSX-T Integration Guide Host-based Mode:
Host-based mode involves deploying the VM-Series firewalls directly on the host machines within the
18/103
NSX-T environment. This allows for direct integration and security enforcement on the host level.
Reference: NSX-T documentation from Palo Alto Networks describes host-based deployment options
for VM-Series firewalls.
