Virtual Machine (VM) migration is an appealing technique on nowadays cloud platforms to achieve high availability, load balancing and power saving. Unfortunately, migration of VM involves transferring a large amount of data, thereby imposing high overheads on network traffic, and consequently results in significant application performance degradation. In this paper, we propose an introspection-based...
More and more applications are providing services in many important aspects of our society, any faults of these applications may lead to enormous losses. Timely detection of faults could reduce the accidental loss and make contributions to fast recovery of systems. There exist many kinds of fault detection techniques, some of them focus on the discovery of fault events but ignore the details of faults,...
Software aging has been cited in many scenarios including Operating System, Web Servers, Real-time Systems. However, few studies have been conducted in long running virtualized environments where more and more software is being delivered as a service. Furthermore, state-of-the-art methods lack the ability to deal with miscellaneous upper applications and underlying systems transparently in virtualized...
