서버는 여러분이 프로그램으로 소비하거나 **활용(utilize)**할 수 있는 **리소스**입니다. CPU의 계산 시간과 사용 가능한 RAM 메모리가 대표적입니다.

시스템 리소스를 얼마나 소비/활용하고 싶으신가요? “많지 않게”라고 생각하기 쉽지만, 실제로는 **크래시하지 않는 선에서 가능한 한 많이** 사용하고 싶을 가능성이 큽니다.

서버 3대를 비용을 내고 쓰고 있는데 RAM과 CPU를 조금만 사용한다면, 아마 **돈을 낭비**하고 💸, **서버 전력도 낭비**하고 🌎, 기타 등등이 될 수 있습니다.

그 경우에는 서버를 2대만 두고, 각 서버의 리소스(CPU, 메모리, 디스크, 네트워크 대역폭 등)를 더 높은 비율로 사용하는 것이 더 나을 수 있습니다.
