Auto Scaling vs Manual Scaling: Who Adjusts Capacity?

Mon, 03 Aug 2026 06:33:25 +0900

Overview

Auto scaling and manual scaling both change how much compute capacity an application has, but they differ in who — or what — decides when that change happens. Auto scaling relies on an automated feedback loop that watches metrics and reacts on its own, while manual scaling depends on human intervention to notice load and issue the change. That difference in decision-maker drives everything else: reaction speed, cost efficiency, and how much ongoing attention the system needs.
