본 연구는 시스템의 부하 특성에 따라 에너지 절감을 최적화하여 에너지 인지형 웹 서비스에 관한 연구이다. 최근에 데이터 센터의 서비스 규모가 점점 커지고 그 응용 범위가 확대되어 이에 따른 에너지 절감에 대한 관심이 증가하고 있다. 특히 이러한 데이터 센터의 서비스 중에서 가장 많은 비중을 차지하는 서비스가 웹 서비스이다. 본 연구는 이처럼 비중이 높은 웹 서비스 부분에서 서비스의 성능을 보장하는 동시에 에너지 절감하는 새로운 기법을 제안한다. 그 제안된 기법은 시스템의 부하에 따른 에너지 소모율의 차이점을 통하여 최적화 하였다. 성능 평가는 실제 서비스에 매우 유사한 조건에서 평가되었고 제안하는 기법이 기존 방식에 비하여 크게는 약 30% 이상의 에너지를 절감을 보여준다.
