"2. Virtualization - Using virtual machines (VMs),
reduces costs in hardware, power, cooling, and break/fix issues
related to hardware. Pound for pound, virtualization shows the
greatest savings of any other technological change you can make to
your infrastructure. The big players in this field: VMware, Citrix,
Sun, and Microsoft.
"3. Open Source Applications - Office Suites, Accounting
programs, High-end Graphics programs, and much more are available
as either free open source or open source format. (Not all open
source programs are free but all include the program's source
code). These days you have a choice and oftentimes the choice is a
free, well-maintained, and Microsoft-compatible application that
offers freedom from licensing prison. The most notable among these
is OpenOffice.org the world-class Office Suite that compares and
competes favorably with Microsoft Office."
