클라우드 컴퓨팅 기술의 발전으로 서버 환경에 한하여 적용되었던 가상화 기술이 데스크탑 환경으로 빠르게 확산되어가고 있다. 클라우드 컴퓨팅 환경은 가상화 기술을 이용하여 하나의 물리적 자원위에서 여러 개의 가상 머신을 운용하기 때문에 효과적인 로드 밸런싱(load balancing) 기법을 필요로 한다. 하지만 기존 서버 가상화 환경에서의 로드 밸런싱 정책은 프로세서와 네트워크 사용률을 주된 로드 측정의 기준으로 삼았다. 그에 반해 데스크탑 클라우드 컴퓨팅 환경 하에서의 데스크탑 가상 머신은 사용자 유형에 따라 다양한 종류의 작업 요청을 처리해야 하기 때문에 처리 중인 작업의 특성을 고려한 보다 유연한 로드 밸런싱 정책을 필요로 한다. 본 연구에서는 데스크탑 클라우드 컴퓨팅 환경에 적합한 로드 밸런싱 정책을 제시하고, 이를 바탕으로 제안하는 기법이 가지는 효율성을 기존 방식과 비교 및 분석 하였다.

Recently, cloud computing is being emerged paradigm that a support computing resource flexible and scalable to users as the want in distributed computing environment. Actually, cloud computing can be implemented and provided by virtualization technology. In this paper, we studied open source based cloud computing and built a educational practice system through cloud computing. Virtualization-based cloud computing provides optimized computing resources, as well as easy to manage practical resource and result. Therefore, we can save the time for configuration of practice environment. In the view of faculty, they can easily handle the practice result. Also, those practice condition reuse comfortably and apply to various configuration simply. And then we can increase capabilities and availabilities of limited resources.

The widespread development of IT, growth of Web 2.0 application, the proliferation of personal hand held devices with access to the internet, and the availability of wireless networks, each have played an important role in creating the cloud computing model. Cloud computing is a business model and new trend of web application technology. The term is often used in the same context as grid computing or utility computing. In the cloud computing environment, we are able to use the same all of hardware resources in the server and share information easily. In this paper, we aimed a study to apply e-learning part to cloud computing environment. For this purpose, we proposed an application of LMS and LCMS based e-learning in the cloud computing environment. So LMS including LCMS connected to data center of cloud computing.

The popularity of cloud computing has led to the emergence of various types of cloud services, and the hybrid cloud, a deployment model that integrates public cloud and private cloud and offset their shortcomings, is in the spotlight recently. However, the complexity of different clouds integration and the lack of related integration solutions have delayed the adoption of hybrid cloud and cloud strategy by companies and organizations. Therefore, in this paper, we propose a cloud integration mechanism to solve the integration complexity problem. The cloud integration mechanism proposed in this paper consists of integration script that solves the cloud integration by the script based on the hybrid cloud function, a process of creating and executing it, and a script creation model applying the software design pattern. By integrating the various cloud services, we can quickly generate scripts that meet the user's needs. It is expected that the introduction of hybrid cloud and the acquisition of cloud strategy can be accelerated through this proposed integration mechanism.

Cloud computing emerges as a new paradigm for deploying, managing and offering IT resources as a service anytime, anywhere on any devices. Cloud computing data center stores many IT resources through resource integration. So cloud computing system has to be designed by technology and policy to make effective use of IT resources. In other words, cloud vendor has to provide high quality services to all user and mitigate the dissipation of IT resources. However, vendors need to predict the performance of cloud services and the use of IT resources before releasing cloud service. For solving the problem, this research presents cloud service modeling on network environment and evaluation index for availability optimization of cloud service. We also study how to optimize an amount of requested cloud service and performance of datacenter using CloudSim toolkit.
