[ale] Thoughts on PC hardware.

[Bob Toxen]

Thanks for mentioning those other free/cheap VMs.  I just could not think of the names
(and should have said "VMware or similar").

There are good reasons to staying current on VMware ESXi and all those tools (since that's where lots of money is).  But the Linux kernel has KVM/QEMU which is what almost every VPS provider uses to avoid VMware's high license costs.

I used to run ESX and ESXi, Xen, VirtualBox, but after switching to KVM/QEMU that is part of the kernel project, the performance and flexibility completely won me over.  Add on libvirt and whatever management system you like (oVirt/VMM/virsh/..../proxmox) and everyone with a minimal laptop can have a VM server.  More hardware gets you more capacity.  At one point, I was running 20 VMs on a Core2 Duo system - and it was fine.

As for redundancy, 2 Ryzen systems with a dedicated LAN interlink can support clustered storage in an N+1 setup.  Hard to be 2 separate, cheap, systems for redundancy, if you limited to a single building.
