In VMware Cloud Foundation, when creating a new VI Workload Domain with a dedicated NSX instance, the NSX Managers are deployed directly within that specific workload domain. Each VI Workload Domain can be configured with its own isolated NSX instance, providing independent network services and avoiding any potential conflicts with other workload domains or the Management Domain.

This approach maintains separation of resources and ensures that each workload domain can be managed and updated independently, enhancing scalability and security within the VCF environment.
