Bootstrapping allows you to create a repeatable and streamlined process of deploying new VM-Series firewalls on your network because it allows you to create a package with the model configuration for your network and then use that package to deploy VM-Series firewalls anywhere. You can bootstrap the VM-Series firewall off an external device (such as a virtual disk, a virtual CD-ROM or a storage bucket such as AWS S3 or Google Cloud bucket) to complete the process of configuring and licensing the VM-Series firewall. You can either bootstrap the firewall with basic initial configuration and licenses so that the firewall can register with Panorama and then retrieve its full configuration from Panorama, or you can bootstrap the complete configuration so that the firewall is fully configured on boot up.
