When Adding More Servers Is Not the Real Answer


When Adding More Servers Is Not the Real Answer

Horizontal scaling solves capacity problems, but not necessarily inefficiency.

Scaling Logic

More servers increase throughput.
They do not reduce per-request cost.

Economic Consideration

Scaling infrastructure without reducing inefficiency increases operational expense.

Architectural First

Reducing execution cost often yields more sustainable improvements.

Load Testing Insight

Measure per-request CPU time before scaling decisions.
