VMUG has cheap licenses for vCenter, as long as it's not for business production. In other words, you can use it for your home lab as long as you aren't making money from it, even though you might consider it as "production".With ESXi you need Vcenter and that’s not free
The problem with nutanix in homelab is that CVMs (controller VM) requires a good chunk of RESERVED memory on each node. My production CVMs are at 32GB each, and still, bitch about low memory. 24GB is a bare recommended minimum. It could run as low as 16GB, but they are not recommending it. My company runs 3 nutanix clusters in production, 2 in data centers, and one 3-node ROBO. All rock-stable and very easy to manage.If you have the hardware and are committed then the Nutanix community edition is very compelling. I ran it in a homelab for a couple years and it was rock-stable.
