Abstract

The concept of Cloud Service Brokerage (CSB) has been introduced as a result of the expansion of the cloud-computing paradigm. Cloud services that provide similar functionality are registered with a CSB. A CSB intermediates cloud services between cloud users and providers. However, there are differences in the price and performance offered by each of the cloud providers. Thus, cloud users have difficulty in finding suitable services to use. Therefore, a CSB is required in order to provide an approach for cloud services to fulfill the requirements of cloud users. In this paper, we propose a virtual cloud bank architecture that includes both a Service Analysis Model (SAM) that can be used to specify and analyze various cloud services and a requirement analysis method that can be used to collect and analyze the cloud user requirements. The VCB architecture that is herein proposed can be used as a reference architecture to provide user-centric cloud services.

클라우드 컴퓨팅 패러다임의 등장에 따라 다수의 클라우드 서비스와 클라우드 사용자를 연계해 주는 CSB(Cloud Service Brokerage) 라는 개념이 제시되었다. CSB 에 등록되어 비슷한 기능을 제공하는 클라우드 서비스들은 제공자마다 성능, 가격 등에 차이가 있으므로, 클라우드 사용자가 클라우드 서비스를 사용하기 위해 적합한 서비스를 찾기 어렵다. 따라서 다수의 클라우드 서비스 중에서 클라우드 사용자의 요구사항에 가장 적합한 클라우드 서비스를 찾아주는 방법을 CSB 에서 핵심적으로 고려해야 한다. 본 논문은 클라우드 사용자의 요구사항을 수집하고 분석하는 방법과 다양한 클라우드 서비스를 명세하는 SAM을 포함하는 CSB 로써 가상 클라우드 뱅크 아키텍처를 제시한다. 본 논문에서 제시한 가상 클라우드 뱅크 아키텍처는 클라우드 사용자의 요구사항에 적합한 클라우드 서비스 제공을 위한 CSB의 참조아키텍처로 활용할 수 있다.
