NodeJS's asynchronous approach is a concurrency (but not parallelism) approach. Your reference to "Pentiums" (which I assume is intended to be a reference to single-core nodes) suggests that your concern is actually with parallelism rather than concurrency.

But, sure, a not uncommon usage pattern for an IaaS like GCE might be to have lots of single-core nodes cooperating, rather than running individual processes on larger nodes with lots of parallel threads.
