VI workload domains support the NSX for vSphere and NSX-T platforms.
NSX for vSphere provides networking and security functionality for your vSphere environment which allows networks and network services to be abstracted from the physical infrastructure. The ability to manage the network through software allows for rapid changes and increased security policies to be implemented.
NSX-T is focused on emerging application frameworks and architectures that have heterogeneous endpoints and technology stacks. NSX-T Data Center allows IT and development teams to choose the technologies best suited for their applications.
