Virtual machines have been widely adapted for high-level programming language implementations and for providing a degree of platform neutrality. As the overall use and adaptation of virtual machines grow, the overall performance of virtual machines has become a widely-discussed topic. In this paper, we present a survey on the performance differences of the two most widely adapted types of virtu...

Abstract This paper presents the invited talk at the "Simposio Brasileiro de Arquitetura de Computadores e Processamento de Alto Desempenho (SBAC'2000)": the Virtual Virtual Machine approach for highly configurable operating systems...

By decoupling network functions from the underlying physical machines (PMs) at edge of networks, virtualized multi-access computing (MEC) enables deployment new services and elastic scaling to reduce maintenance costs in a more flexible, scalable cost-effective manner. Although there are appealing performance gains be achieved, placement virtual (VMs) on top sharing PMs support computation-inte...

Due to the large-scale development of cloud computing, data center electricity energy costs have increased rapidly. Energy saving has become a major research direction virtual machine placement problems. At same time, multi-dimensional resources on should be used in balanced manner order avoid waste. In this context, paper addresses real-world problem arising Healthcare-Cloud (H-Cloud) hospital...
