We touched on Hyper-convergence in 2017 in this article. There has been a dramatic increase in installations and also vendors offering the service. Microsoft with its Storage Spaces Direct (S2D) offering taking on Vmware VSAN.
Netapp has been a new player to the game with Nutanix being still the strongest player per below
One of the main benefits we have seen with Nutanix is the cost of the Open Source operating system Nutanix AOS compared to Vmware. Nutanix can run Hyper-V or Vmware but the only benefit you entail then is the bonding hardware ( Storage , Compute and Networking )
We are definitely seeing a shift of Small to Medium Business using more cloud offerings with Compute in Azure and larger Enterprise using the above systems!
