Abstract
Cloud computing provides flexible and efficient mass data analysis platform. In this paper, we define a new resource provisioning architecture in the public cloud, named PCIA. In addition, we provide a service model of PCIA and its new naming scheme. Our model selects the proper number of physical or virtual resources based on the requirements of clients. By the analysis of performance variation in the PCIA, we evaluate the relationship between performance variation and resource provisioning, and we present key standards for cloud system constructions, which can be an important resource provisioning criteria for both cloud service providers and clients. ∙제1저자 : 윤빈풍 ∙교신저자 : 곽종욱 ∙투고일 : 2014. 1. 9, 심사일 : 2014. 1. 28, 게재확정일 : 2014. 2. 3. * 영남대학교 기계공학과(Dept. of Mechanical Engineering, Yeungnam University) ** 영남대학교 컴퓨터공학과(Dept. of Computer Engineering, Yeungnam University) 2 Journal of The Korea Society of Computer and Information February 2014 Application Layer (SaaS) Platform Layer (PaaS) Virtualization Infrastructure Layer (IaaS) Virtual Computing Resources Virtual Storage Resources Virtual Network Resources Public Cloud Intranet Private Cloud Intranet Hybrid Cloud Intranet 그림 1. 클라우드컴퓨팅모델의계층적구조 Fig. 1.
