Abstract

Cloud Computing Service should support efficiency and stability. United States of America, for example, provides FedRAMP (Federal Risk and Authorization Management Program) accreditation to certify cloud computing service and hence growth of computing service industry is giving benefits of cost reduction and efficiency to companies. However, the use of computing service brings more risk than ever. Because cloud computing holds all the data of multiple companies, problems such as hacking bring out control loss of service and as a result total data of companies can be lost. Unfortunately, cloud computing certification programs do not have any good solutions for this data loss and companies may lose all the important data without any proper data backup. This paper studies such problems in terms of backup problem and provides Data Availability Zone solution for recovery and safe saving of data so that computing service can offer better efficiency and stability.

클라우드 컴퓨팅 서비스는 그 효율성과 안정성이 기반이 되어야 한다. 한 예로 미국은 클라우드 컴퓨팅 서비스의 안전성을 위하여 FedRAMP 인증을 제시하고 클라우드 컴퓨팅 서비스 산업의 성장은 많은 기업들에게 비용 절감과 업무의 효율성을 제공하고 있으나, 그에 따른 위험성 역시 높아지고 있다. 해킹 등으로 클라우드 서비스 특징상 데이터에 대한 통제성을 잃게 되고, 많은 데이터가 한 곳에 몰리는 현상은 장애가 발생하면 모든 기기의 데이터가 일제히 삭제되는 되는 문제점이 있다. 본 논문에서는 클라우드 보안 인증 제도의 비즈니스 연속성의 문제점을 알리고 이를 위한 솔루션인 서비스 가입자 내부에 백업과 외부 백업의 장단점을 비교한다. 결론적으로 외부 백업이 구조상으로 우위에 있음을 보인다.
