Proactive Software Rejuvenation Solution with Enhanced VM Migration Decision in IT Infrastructure Paing, Aye Myat Myat Lwin, Khin Moh Moh Thein, Ni Lar The availability of IT infrastructures is stilla huge challenge nowadays. As servervirtualization is used as an essential softwareinfrastructure of various software services in ITenvironment and it is emerging as a technique toincrease system reliability and availability. Toprevent system failures caused by softwareaging, software rejuvenation can be applied invirtualized environment. Software aging ofvirtual machine monitors (VMMs) is becomingcritical because performance degradation orcrash failure of a VMM affects all virtualmachines (VMs) on it. Live VM migrationenables a running VM on a host server to moveonto the other host server with very smallinterruption of the execution. VM migrationdepends on a variety of criteria and efficientdecision support is required. The work presentedin this paper aims to offer the high availabilityagainst software aging of virtualized serversystem by providing VM migration based VMMsoftware rejuvenation solution. First, we presentthe resource usage as accepting as manyservices as in virtualized environment whichsupport of VM migration. Second, we presentmigration based VMM rejuvenation analyticmodel and evaluate the steady-state systemavailability based on familiar Markoviananalysis through the use of numerical analysis. 2012-02-28 http://hdl.handle.net/20.500.12678/0000004712 https://meral.edu.mm/records/4712
