Virtualization is an innovation that has widely been utilized in modern data centers for cloud computing to realize energyefficient operations of servers. Virtual machine (VM) migration brings multiple benefits such as resource distribution and energy aware consolidation. Server consolidation achieves energy efficiency by enabling multiple instances of operating systems to run simultaneously on...

This paper aims at developing a honeypot system for web applications. The key idea is employing migration techniques to create a virtual machine as a honey web server, and making the honeypot to equip the same memory and block content of the real systems. Recently, web applications have been the target of numerous cyber attacks. In order to catch up new vulnerabilities in the applications, usin...

We present two strategies to balance the load in a system with multiple virtual machines (VMs) through automated live migration. When the push strategy is used, overloaded hosts try to migrate workload to less loaded nodes. On the other hand, when the pull strategy is employed, the light-loaded hosts take the initiative to offload overloaded nodes. The performance of the proposed strategies was...

In this paper we present ARRIVE-F, a novel open source framework which addresses the issue of heterogeneity in compute farms. Unlike the previous attempts, our framework is not based on linear frequency models and does not require source code modifications or off-line profiling. The heterogeneous compute farm is first divided into a number of virtualized homogeneous sub-clusters. The framework ...

Remus was the first system which implemented whole virtual machine replication to achieve high availability (HA). Recently a fast, lightweight migration mechanism (LLM) was proposed to reduce the long network delay in Remus. However, all these virtualized systems have the long downtime problem, which becomes a bottleneck to achieve HA. Based on LLM, in this paper we describe a fine-grained bloc...

This paper addresses the issue of how to meet the strict timing constraints of (soft) real-time virtualized applications while the Virtual Machine (VM) hosting them is undergoing a live migration. To this purpose, it is essential that the resource requirements of a migration are identified in advance, that appropriate resources are reserved to the process, and that multiple VMs sharing the same...

Cloud Computing shares computing resources to execute application. Cloud systems provide high-specification resources in the form of services, leading to the provision of user convenience and greater ease for personal-computer users; however, expansions of the cloudsystem service necessitate a corresponding enhancement of the technology that is used for server-resource management. In this paper...

Marshallese mobility long precedes the deep disruptions of nuclear history, contemporary climate-induced migration debates, and ongoing socio-economic, legal, geopolitical discourses about freely associated relationship between Republic Marshall Islands (RMI) United States (U.S.). Nonetheless, understanding well-being people today requires an acknowledgment multiple factors that have drawn at l...

Live-migration has become a common operation on virtualized infrastructures. Indeed, it is widely used by resource management algorithms to distribute the load between servers and to reduce energy consumption [1, 2]. Operators rely also on migrations to prepare production servers for critical maintenance by relocating their running VMs elsewhere. To apply new VM placement decisions, livemigrati...
