Your brain as a cloud stack: white matter is IaaS, thalamus is the API gateway

- A Reddit long post maps brain anatomy onto cloud computing tiers for neuroanatomy + compsci readers:
- IaaS: white matter = high-speed cabling between regions (myelin as insulation, top speed 120 m/s); glial cells = hardware maintenance; blood-brain barrier = physical-layer firewall; cortical neurons = raw compute.
- PaaS: thalamus = API gateway filtering and routing sensory input (except smell); basal ganglia = scheduler and permission layer; brainstem = OS kernel running breathing and heart rate; cerebellum = runtime optimizer.
- SaaS: prefrontal cortex = executive user-facing app; Broca's/Wernicke's areas = communication software; sensory cortices = media processing; association cortex = creative suite; hippocampus = cache-to-cloud storage sync.
- The author adds a correction: white matter signals are fast but not light-speed — "high-speed" is more accurate.
