Network virtualization ; Do I go for NVGRE or VXLAN with vNext?

With Windows 2016 / vNext the network virtualization has made a fundamental change… In 2012 Microsoft only supported its own NVGRE protocol. With the upcoming release, Microsoft will support both NVGRE and VXLAN! It even goes so far that VXLAN will be the default protocol. So in terms of VHS vs Betamax, we can conclude that Microsoft has decided that the market is more in favor of VXLAN.
  
What does that mean for organizations that have already implementee NVGRE? Both protocols will be supported by the typical Mellanox of Chelsio adapters in terms of translations. The HNV (Hyper-V Network Virtualization) will also support both simultaneously. Though if you are looking to start a new implementation, it is best to go for VXLAN now!
