VM information sources provides an automated
way to gather information on the Virtual Machine (VM) inventory
on each monitored source (host); the firewall can monitor the VMware
ESXi, vCenter Server, AWS-VPC, Microsoft Azure VNet, and Google
Cloud. As virtual machines (guests) are deployed or moved, the firewall
collects a predefined set of attributes (or metadata elements) as
tags; these tags can then be used to define Dynamic Address Groups
(see
Use
Dynamic Address Groups in Policy) and matched against in
policy.
