Executive Summary This paper provides a deep look at the performance implications of the live storage migration of a VM running a large SQL Server database workload. Performance of the workload when migrating different components of the database (data, index, and log) was measured and compared against the steady state performance (when there was no migration). Experiments discussed in this pape...

Cell migration is an essential feature of metazoan development and also plays important roles in the physiology of adult organisms (Lehmann, 2001; Locascio and Nieto, 2001). Impaired cell migration results in various developmental disorders such as congenital brain defects, and excessive migration also contributes to pathologies such as tumor metastasis (http://www.cellmigration .org; Yamaguchi...

Green cloud data center has become a research hotspot of virtualized cloud computing architecture. And load balancing has also been one of the most important goals in cloud data centers. Since live virtual machine (VM) migration technology is widely used and studied in cloud computing, we have focused on location selection (migration policy) of live VM migration for power saving and load balanc...

According to the latest census conducted by the United Nations, currently about 213 million people, i.e. more than 3 percent of the world's population, live outside the country of their birth. The great mobility of the population has definitely different effects on host countries’ economy. The labor market along with commodity, capital and money markets as one of the main pillars of the e...

Live virtual machine migration is a powerful tool offered by virtualization technologies. However, current implementations restrict its usage to local area networks. Extensions to wide-area networks have been proposed with systems for transferring disk state and transparently migrating network connections. Still, wide-area live migration remains expensive to use because of the bandwidth bottlen...
