Figure 5: Moen tangible and intangible benefits during implementation of virtual servers [ 2].
The pilot team will test-drive the systems and test functionality in an
operational or small subset of systems. Pilots can promote virtualization success by sharing early wins with project management.
Successful pilots allow users and project teams to gain valuable experience that will come in handy during full-scale production roll-outs.
Virtual machines have enjoyed a special niche within the information
technology community over the years. Systems engineers and developers have continued to support virtual machines and push innovation in new ways. Virtual machines are gaining wider acceptance due
to new efficiencies, ease of use, and users’ demands for flexibility.
Hardware, software, and operating system (container) virtual server
technology are among the various virtual machine implementations.
There is no “one size fits all” virtual machine solution. Rather, many
options are designed around specialized approaches. Hardware
advances such as the AMD Opteron dual-core processors are making
it possible to build powerful servers to host guest operating systems.
Intel’s Vanderpool and AMD’s Pacific next-generation architecture
will allow more flexible virtual systems at the hardware level.
Data centers and IT management are implementing virtual server
technology, often as part of a consolidation strategy. Cost savings in the
areas of software license management, systems management, data center, and overhead costs, such as electricity, generators, and floor space are
key benefits for consolidated virtual server environments. IT managers
trying to contain server sprawl, standardize and control systems, and
build strategic platforms see virtual machine technology as an enabler.
Virtual storage area networks and grid computing are taking virtual machines to new levels. Advanced technologies such as high-performance computing, grid computing, and service-oriented
architectures with dynamic allocation of resources are complimentary
solutions to virtual machines. From its inception on the mainframe to
distributed servers on x86, the virtual machine has matured and will
play an increasing role in systems management.
