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.

Key Takeaways

  • Scale after optimizing structure.
  • Separate throughput from efficiency.
  • Analyze cost per request.
  • Infrastructure should amplify good architecture.
