Efficient and enhanced byzantine fault detection and tolerance algorithms for cloud computing services

Abstract

Cloud Computing is an essential resource which is the complete requirement for this forth coming century where users can access their applications or software whenever and wherever they required In this way Cloud Computing distinguishes itself from other distributed computing paradigm through offering services on demand basis without any geographical restrictions through virtualization Virtualization is the process of creating one or more virtual objects or entities for a single physical component such as computing hardware storage devices and computing network resources It helps to utilize the resources to its maximum potential and availability It revolutionizes the computing by offering services to a wide variety of customers starting from the casual users to large scale business oriented industries In spite of its capabilities Cloud Computing still struggles with handling a wide array of faults and this causes loss of credibility to Cloud Computing Among those faults Byzantine faults offers serious challenges to the fault tolerance mechanism because these often goes undetected at the initial stage and it can easily propagate to other VMs Byzantine faults in cloud computing is a serious problem because of the fault propagation possibility existence which makes the fault to propagate surreptitiously through consecutive virtual components still it spreads throughout the entire cloud system The real world problem which is faced by the cloud computing management has more serious and are beyond typical human narratives thus making it an unprecedented and unpredictable challenges Consequently some of the mission critical applications such as air traffic control online banking video streaming in online etc are still staying away from the cloud for such reasons newline
