초록

클라우드 서비스가 확대되고 있지만, 많은 이용자들은 클라우드 서비스의 도입에 어려움을 겪고 있다. 이는 이용자 입장에서 어떤 클라우드 서비스를 신뢰할 수 있는지에 대한 정보가 없기 때문이다. 클라우드 서비스수준협약(클라우드 SLA)은 클라우드 서비스를 제공하는 공급자와 이용자간에 서비스의 품질과 성능 등을 포함한 정성적인 지표와 정량적 지표를 이용하여 협의하는 것이다. 이 연구에서는 클라우드 서비스 사업자의 서비스 수준을 향상하고 이용자를 보호하기 위해 국내 클라우드 산업에 적용할 수 있는 클라우드 SLA를 위한 프레임워크 제안하고 이를 이용하여 국내 클라우드 산업에 적용할 수 있는 클라우드 SLA의 세부 구성항목을 도출하고자 한다. 이를 통해 정부의 "클라우드컴퓨팅 발전 및 이용자 보호에 관한 법률" 체계하의 클라우드 서비스 제공자와 이용자간의 신뢰도 향상을 위한 정책적 활용은 물론 궁극적으로 국내 클라우드 서비스의 품질 성능 수준 향상 및 이용자 신뢰기반 조성을 통해 클라우드 서비스의 활성화를 기대한다.

While cloud services are expanding, many users are having difficulty in adopting cloud services. This is because there is no information as to which cloud services can be trusted by users. loud service level agreement (Cloud SLA) is an agreement between cloud service providers and cloud service consumers using qualitative and quantitative indicators including quality and performance, etc. of cloud services. In this study, we propose a framework for cloud SLA that can be applied to the domestic cloud industry to improve service levels for cloud service providers and to protect users and also derive the detailed components of cloud SLA applicable to the domestic cloud industry using the proposed framework. Through this result, it is expected that the government will utilize the policy to enhance the reliability between cloud service providers and users under "the Act on the Development of Cloud Computing and Protection of Users", and eventually to activate cloud services by improving the quality and performance level of domestic cloud services and building a user trust.
