| 摘要: | 隨著網際網路的不斷演進，人類對資訊的需求與日俱增，加上虛擬化的發展，與近年來雲端的崛起，公有雲則越來越盛行，許多公司開始爭相研發雲端設備，如Amazon EC2、Windows Azure等發展起來雲端大廠，使得利用公有雲的企業與用戶越來越多。因上述雲端的崛起，小型企業通常要使用雲端會先建立起私有雲再考慮是否應該跨雲，本研究前身CSEP雲端安全實驗平台就是利用私有雲虛擬化的特色，打造出保存與還原當時的環境，達到讓學員可以輕易的體驗與操作經典的資訊安全案例為目的的平台進行研究。
但是要達到讓使用者體驗經典的資訊安全案例，量身打造當時環境是教材設計者最為花費時間的步驟，隨著私有雲的負載量持續增加，倘若要繼續提供服務勢必要擴充自己私有雲的設備或者在公有雲上重新打造之前設計之案例，但因擴充私有雲會耗費更多的成本，而在公有雲上重新打造眾多案例的環境在人力和需時上是根本無法達到的。
以上的環境直至今日的研究仍未不足的地方如：遷移至公有雲的技術、雲端供應商所提供的系統不合等等，因此本研究針對以上的不足實驗並研究這一類的問題，並通過實際遷移虛擬機至Amazon EC2上來測試出效能、相容性以及與原先Xen架構下的虛擬機有何不同來實現私有雲遷移公有雲之意義。
People's demand for information gains day by day because of the evolution of Internet. Also, the development of virtualization and the rise of the cloud, especially public cloud, are popular every day. Many companies began competing the cloud equipment against each other, such as Amazon Ec2, Windows Azure and other developing cloud manufacturers. As a result, there were more and more business and users using public cloud. Due to the rise of cloud which mentioned before, small businesses had to build a private cloud, and then, consider whether it should cross the cloud or not. The predecessor of this research, CSEP Cloud of Security Experimental Platform, is using the feature of virtualization in order to create a environment at that time and save it. Which make sure students could easily experience information security and operate the platform which built for classic case for the purpose of research.
The amount of burden of private cloud is continuing growing. It will cost a lot to expand equipment for private cloud if people wish to go on providing this service. But, it's impossible to build so many environmental cases on public cloud because of human ability and demand of time.
The environment which mentioned above is still have lots of defects. Such as technology for moving private cloud to public cloud, the old system is not compatible with the system which cloud provider provided, etc.. Therefore, the research points out the problem above, with further research and experiment. Also, we test the proficiency, compatibility by our successfully moving virtual machine to Amazon EC2. By doing so, people will know the meaning of moving private cloud to public cloud, and also, knows how difference between it and original virtual machine which is Xen Architecture. |
