Abstract

Web server cluster systems are widely used, where a large number of PC level servers are interconnected via network. This paper focuses on forecasting an appropriate number of web servers which can serve four different classes of user requests, simple web page viewing, knowledge query, motion picture viewing and motion picture uploading. Two ways of serving different classes of web service requests are considered, commonly used web servers and service dedicated web servers. Computer simulation experiments are performed in order to find a good way of allocating web servers among different classes of web service requests, maintaining certain levels of resource utilization and response time.

PC급 성능의 서버를 네트워크로 연결하여 대규모 웹서비스에 사용하는 웹서버 클러스터 시스템이 널리 활용되고 있다. 본 논문은 단순 페이지 뷰, 지식 탐색, 동영상 뷰 및 동영상 업로드 등 4가지 형태의 웹 서비스를 제공하는 대규모 웹서버 클러스터 시스템을 대상으로 공동 사용 방식과 전용 사용 방식을 적용할 경우 각각 필요한 웹서버 규모를 예측해 본다. 이를 위해 일정한 수준의 자원 활용률을 유지하면서 응답시간을 짧게 유지하는 서버 배치 방안을 컴퓨터 시뮬레이션 실험을 통해 모색해 본다.
