본 논문은 클라우드 컴퓨팅 기술 동향에 대한 분석서로 관련 기술과 주요 서비스 내용을 소개한다. 2006년 클라우드 컴퓨팅이란 용어가 처음 생겨난 이래, 2008년 글로벌 IT 기업 CEO들이 잇달아 차기 비즈니스의 핵심 기술로 클라우드 컴퓨팅을 지목한 이후, 전세계가 클라우드 컴퓨팅에 대한 관심이 집중되고 있다. 이에 클라우드 컴퓨팅의 대표 서비스 형태인 IaaS, PaaS, SaaS 서비스에 대한 개념을 설명하고, 각 서비스별 대표 기업들의 기술 동향을 살펴본다. IaaS 서비스에 대해서는 아마존의 EC2와 S3 서비스를, PaaS 서비스에 대한 Google의 AppEngine을, SaaS 서비스로 세일즈포스닷컴의 세일즈포스 서비스를 대표 기술로 소개하고 클라우드 컴퓨팅을 구성하기 위한 기술적인 요소들을 간략하게 언급하였다.
