With NSX Federation, you can federate NSX environments across VMware Cloud Foundation (VCF) instances. You can manage federated NSX environments with a single pane of glass, create gateways and segments that span VMware Cloud Foundation instances, and configure and enforce firewall rules consistently across instances.
Important: If you plan to deploy vRealize Suite components, you must deploy Application Virtual Networks before you configure NSX Federation. See
Deploying Application Virtual Networks in VMware Cloud Foundation.
