These days, the rising interests in green IT, coupled with cost-cutting needs, has opened the door for growth in one particular area of technology: server virtualization.
Virtualization is being praised for helping achieve environmentally-friendly technology goals by reducing the number of physical servers a company must house onsite – thereby reducing power consumption. It's also being lauded as a big money-saver for IT operations in general. And the popularity of the technology is expected to increase significantly in the coming year and beyond, as companies become more familiar and comfortable with it.
If you're looking to specialize in a hot area of technology, this is one of those areas you should really be checking out, especially if you already have system administration or network administration experience, and if you're already familiar with some of the mainstream virtualization technologies out there, including those marketed by VMWare, Citrix and Microsoft.
