Virtualization is one of the prevailing trends in Information Technology (IT) for several reasons. First, the technology provides for the consolidation of IT resources. Rather than having server capacity and dedicated staff at every location within the enterprise, all necessary servers can be consolidated to one location and run through the enterprise cloud.
Furthermore, the consolidation goes even further by reducing the number of physical servers required to support the corporate mission. By running virtual servers as images on physical machines, servers can scale to use different amounts of memory, disk space and processing power, even spanning physical machines if necessary.
Another advantage of virtualization is the opportunity to offload IT staffers from the payroll. Since one person can administer more servers than ever, payroll is reduced and precious office space can be reassigned to other profit centers within the enterprise.
Finally, regardless of whether or not the political arguments that promote the theory of "climate change" have any merit, one thing is for sure: being able to lay claim to a green corporate environment is prestigious and profitable from a marketing perspective. Virtualization is "green" by nature, giving companies some extra credibility in the marketplace.
In order to enjoy the advantages of virtualization, however, certain challenges to server virtualization management must be dealt with. Just a few of these challenges are listed below.
