Research Paper (postgraduate) from the year 2008 in the subject Technology grade: A+ Capilano University (Capilano University Canada) language: English abstract: Virtualization is a new and emerging technology that is rapidly growing taking industry bystorm. In business virtualization has become a new buzz word but not many decision-makersactually understand what it is. In today's fiercely competitive world it is crucial for decisionmakersto learn more about virtualization to see if it can give their organizations leverage overtheir competition. Not only that virtualization can save businesses of all sizes a lot of money. Summed up in one sentence virtualization is an information technology (IT) logistics strategythat can save businesses time and money. Today most IT data centers use one machine for oneserver (e.g. one machine to serve e-mail one for data one for the website etc.) causing serversprawl. Eventually businesses run out of room for new machines leaving them stuck in a badposition. With virtualization each server's programs files and processes are merged into onefile (an image) and is then placed among other images on one machine. Consolidation of ITresources improves server utilization and consequently increases efficiency lowers theelectricity bill and reduces physical footprint. It also makes deploying new servers cheap. Adifferent approach to virtualization is making multiple physical resources appear as one physicalresource simplifying data-center operations and network administration through oneconsolidated virtual environment.The advantages of virtualization are almost infinite but the main points are business continuitysaving money through outsourcing data-processing (cloud computing) and preserving legacyapplications. The disadvantages are possible security problems an initial investment up-frontand uncertainty about the roll-out process (e.g. bugs that take time to work out).
