The one thing that HPC (and VFX) have over anyone else, is rational thought. A thing is used because it is the very fastest. we know its fast because we have the numbers to prove it. Infiniband is expensive, but it's much faster than ethernet for DMA. HTTP is far to inefficient for MPI. Posix file systems are brilliant. Object storage is far to slow and unreliable (see Http) ans usually miss important features like locking or concurrent access. when you're paying by the hour, that 5-30% VM/bytecode penalty is ruinously expensive.
