    • Achieving Intelligent Traffic-aware Consolidation of Virtual Machines in a Data Center Using Learning Automata 

      Jobava, Akaki; Yazidi, Anis; Oommen, John; Begnum, Kyrre (IEEE conference proceedings, 2016)
      Cloud Computing (CC) is becoming increasingly pertinent and popular. A natural consequence of this is that many modern-day data centers experience very high internal traffic within the data centers themselves. The ...
    • Management of high availability services using virtualization 

      Braastad, Espen (Høgskolen i Oslo. Avdeling for ingeniørutdanningUniversitetet i Oslo, 2006)
      This thesis examines the use of virtualization in management of high availability services using open source tools. The services are hosted in virtual machines, which can be seamlessly migrated between the physical nodes ...
    • Maximizing hypervisor scalability using minimal virtual machines 

      Bratterud, Alfred; Haugerud, Hårek (IEEE Computer Society, 2013)
      The smallest instance offered by Amazon EC2 comes with 615MB memory and a 7.9GB disk image. While small by today's standards, embedded web servers with memory footprints well under 100kB, indicate that there is much to be ...
    • On achieving intelligent traffic-aware consolidation of virtual machines in a data center using Learning Automata 

      Jobava, Akaki; Yazidi, Anis; Oommen, John; Begnum, Kyrre (Elsevier, 2018-01)
      Unlike the computational mechanisms of the past many decades, that involved individual (extremely powerful) computers or clusters of machines, Cloud Computing (CC) is becoming increasingly pertinent and popular. Computing ...
    • Reliable modeling of CPU usage in an office worker environment 

      Hammer, Hugo Lewi; Yazidi, Anis; Begnum, Kyrre (Association for Computing Machinery, 2016)
      In this paper, we present a novel and realistic model for modelling CPU usage of virtual machines on a cloud. The model is based on considering the CPU consumption of a virtual machine as a one generated from a Hidden ...
    • Simplified cloud-oriented virtual machine management with MLN 

      Begnum, Kyrre (Springer Verlag, 2010-03-25)
      System administrators are faced with the challenge of making their existing systems power-efficient and scalable. Although Cloud Computing is offered as a solution to this challenge by many, we argue that having multiple ...
    • Towards automatic management and live migration of virtual machines 

      Mevåg, Ingard (Høgskolen i Oslo. Avdeling for ingeniørutdanningUniversitetet i Oslo, 2007)
      This project will concider management of a Xen-based virtual infrastructure in several aspects. First, management of the infrastructure itself with configuration and provisioning of virtual machines, followed by a ...
