The foundation of the Network virtualization layer for VCF on VxRail is provided by NSX-V or NSX-T. The Management domain supports NSX-V only, but the VI WLD domains can use either NSX-V or NSX-T. These solutions provide a software-defined networking approach that delivers Layer 2 to Layer 7 networking services (for example, switching, routing, firewalling, and load balancing) in software. These services can then be programmatically assembled in any arbitrary combination, producing unique, isolated virtual networks in a matter of seconds. NSX-T is considered the next generation and provides additional features that NSX-V does not provide. For multi-cloud connectivity and security, NSX-T should be deployed in the VI WLD as NSX-V has no multi-cloud support. NSX-T provides native support for Kubernetes, PKS, and Cloud Native applications.
