Isn't there a meaningful sense in which "separate VMs for different apps" constitutes a cluster? The "cooperative task" they're engaged in is just, broadly, meeting your needs, whatever they are. The isolation is a desirable property, and I agree this is much preferable to a highly inter-coupled bunch of machines, and also that thia stretches the typical sense in which we refer to a "compute cluster", but I don't think it's an entirely invalid framing of the term. |

Not really. In my experience clustering implies multiple compute elements serving the same function with a coordination mechanism to provide redundancy and/or enhanced capacity.
JBOD vs. RAID.
