Workload Distribution Technique in Virtualized Data Center Using Consolidation and Migration

Abstract: To increase the efficiency of energy in data center server consolidation technique is used but due to this technique workload performance degraded .So to improve workload performance we used consolidation and migration in virtualized data center. In consolidation technique minimize the number of physical machine(PM)and maximize the number of virtual machine (VM).To increase number of VM VMWARE is used .it create multiple VM on single PM. So, automatically workload distributes and it required less energy for performance. For this purpose two modules are used 1).consolidation planning module, which gives set of workload, minimize the number of PM by an integer programming model 2). Migration planning module which gives workload from consolidation module to VM by Polynomial time algorithm. LSAP(Linear sum assignment problem )this method used to solve migration mapping problem (means during migration from one VM to another it require more communication cost because destination VM already associated with other VM automatically communication cost increase)in this method created matrix solve by using Hungarian algorithm, will get less migration cost.

Keywords: virtual machine, physical machines, consolidation, migration etc.
