Virtualized Squashed Complexity Sausage

Virtualized Squashed Complexity Sausage:
Straight from RFC 6670 (section 3.4):

[...] as is usually the case with communications technologies, simplification in one element of the system introduces an increase (possibly a non-linear one) in complexity elsewhere. This creates the "squashed sausage" effect, where reduction in complexity at one place leads to significant increase in complexity at a remote location.

This is probably the most concise description of the great idea of using long-distance vMotion for “mission-critical” craplications, and applies equally well to the kludges used to compensate the simplicity of virtual switches.
