VIRTUAL MACHINE MONITORS IMPROVE YOUR CLOUD PERFORMANCE

Abstract:

Cloud computing is quickly becoming the platform of choice for many web services. Virtualization is the key underlying technology enabling cloud providers to host services for a large number of customers.Effective resource management for shared storage systems is challenging, even in research systems with complete end-to-end control over all system components.We evaluate the effectiveness of our implementation using quantitative experiments, demonstrating that this approach is practical.In this paper, we presented a novel I/O workload based performance attack which uses a carefully designed workload to incur significant delay on a targeted application running in a separate VM but on the same physical system. Such a performance attack poses an especially serious threat to data-intensive applications which require a large number of I/O requests.Hence, no hypervisor is needed to allocate resources dynamically,
