It's not a great story from a vendor's perspective either. I work for a big OEM so we chuck a lot of business in VMware's direction, we've been developing various features/products that make use of VMware so we've been making use of NFR licensing for years. But it looks like Broadcom are happy to ditch/sour relationships with vendors too. They've listed extremely specific use cases that you can use NFR licensing for and seems we now fall just outside that and either have to purchase licensing or find alternatives.
Doing some pricing research online, for 12 new servers I've speced up to buy, which totals just under 800 cores comes up with a price of around $100,000 a year for vSphere licensing.
I'm all for bashing BC, but that works out at $125 per year, per core for vSphere. Not sure where your numbers are from, but thats wildly expensive for vSphere.
VVF is RRP'd at $150 a core and that is vSphere, vSAN and some of the vRealise/Aria products. I'd be shopping round if those are the prices you're seeing.
