  4. What is Grid? “ 지리적으로 분산된 고성능 컴퓨터, 대용량 DB 및 첨단 장비 등의 정보통신자원을 고속 네트워크로 연동하여 상호공유/이용할 수 있도록 하는 신 정보 SOC (4As)” • Advanced Network(지능화된 네트워크, GRID 네트워크) • Advanced Computer & Equipment(고성능 컴퓨터와 최첨단 장비) • Advanced Application(차세대 응용과제, GRID 응용 프로젝트) • Advanced Human Resource(과학기술인력, GRID 이용능력 보유자)

  5. Grid Concept at the view of system engineers

  6. Middleware Directory And Security Servers Transaction Servers User Web Application Servers Edge Servers Web Presentation Servers Data Servers Researcher Business Storage Grid Concept at the view of vendors • On-Demand Computing

  9. Basic Grid Services • uniform and versatile authentication, authorization, and security services • standardized access to data archives and services for data location management • standardized access to compute resources • dynamic construction of execution environments supporting complex distributed applications • services supporting construction and management of collaborations (virtual organizations)

  10. Main Features of Grid Middleware • 그리드 보안 시스템 • 그리드 정보 서비스 시스템 • 컴퓨팅 자원 관리 시스템 • 그리드 미들웨어 툴킷 공통 기본 라이브러리 • Run-time 시스템 • 글로벌 큐잉 시스템 • 어플리케이션에 따른 PSE • 대규모 데이터 관리 시스템 • 사용자 서비스 시스템 • 그리드 미들웨어 패키지화
