Abstract:	近年雲端服務的應用逐漸普及到企業內部,越來越多的企業開始將公司內部的服務轉移到私有雲或是公有雲上面,而混和使用公有雲及私有雲是常見的雲端基礎建設需求,通常在私有雲上面的服務,大多是重要且不能中斷的服務,只要發生重大故障導致服務不能運行,企業都會蒙受重大的損失,故雲端平台的可用性 (Availability) 將會變得非常重要,不論是針對系統設備的意外狀況處理,或是維護時的服務轉移,可用性相關的技術都能夠提供許多的幫助,讓企業在面對大型基礎建設的災害時不會顯得措手不及。本研究主要基於國立中央大學平行與分散計算實驗室所開發的 NCU MFTVM 容錯系統進行後續的開發,該容錯系統亦屬於面相雲端服務高可用性的一種技術,而本研究則針對原先的功能進行優化與改善,針對虛擬硬碟同步技術的代價進行優化,以及改善長久開發所累積的技術債,針對系統架構進行部分改良,藉此降低後續開發人員進行開發的負擔。;In recent years, more and more enterprises migrate their services to Cloud platform. And a hybrid Cloud platform is a popular option for enterprises to build their own infrastructure. Basically, their will deploy their core services on private cloud but not public cloud. When any services on a cloud are unavailable, the enterprise may lose a bundle before all services are recovery. Therefore, the availability of cloud platform become more important when services is used on business. This research is based on the NCU MFTVM fault-tolerant system developed by the Paral- lel and Distributed Computing Laboratory of National Central University. We develop a new method to synchronize block with a lightweight mechanism which can reduce the time we need to create a new checkpoint. And we also reengineer a part of our fault-tolerant system to improve the readability and the maintainability.
