Description | ||||||
Worldwide, businesses continually increasetheir dependence on IT systems for routine businessprocesses. The business processes which directlyrely on information systems and the supporting ITinfrastructure often require high levels ofavailability and recovery in the case of plannedand unplanned outage. High availability hasachieved by host per host redundancy, a highlyexpensive method with hardware and human costs.Virtualization technologies promise cost reductionthrough resource consolidation. By combiningvirtualization and HA clustering, it is possible tobenefit from increased manageability and savingfrom server consolidation through virtualizationwithout decreasing uptime of critical services.Using analytical modeling, we analyze multipledesign choices when dual physical servers are usedto host multiple virtual machines. We use Markovdecision process when we are concerned aboutoptimal decision at any arbitrary time. Numericalexamples are presented to illustrate theapplicability of the model. | ||||||
