The solution is only sold as part of a bundle and not as an individual product. Some customers only need vSphere or NSX for their use cases, but account executives focus on bundles so this is a problem. Account executives need to talk with both systems and security staff to get a full picture of the environment's requirements. For example, systems staff have no need for the solution so they will never deploy it.

Hybrid Consultant at Bechtle

There's generally quite a lack of specialists in this space. One of the challenges as a reseller is that I need technical people to go and offer in-depth conversations about the products. We would engage someone to do that, or we would look for some engineering resources to be able to do the implementation. Unfortunately, there are not a lot of those. There is a massive skill shortage. It's a good product, but the way that it has got so many multiple levels that need to be purchased makes it expensive and cumbersome. They seem to value shareholders more than customers, but most corporations seem to do that anyway.

VMware NSX T/V Consulting Engineer /Solutions Architect at Onebox Solutions

The most valuable features are: * N-VDS Geneve encapsulation L2/L3 * Less need for the VM to hit the TOR switch to communicate with VMs on the same ESXi host/segment (logical switch) * Micro-segmentation capabilities/tagging * NSX-T dashboard/compute usage across the configuration allows a quick view * The NSX-T configuration screens are fairly easy to navigate but they might need to simplify them a bit in future versions. * Very extensive detailed configuration items can be set in Uplink profiles to better map pNICs * Edge TEP and Host TEP tunnel config and troubleshooting is much more understandable and verifiable
