Server virtualization, also
known as hardware virtualization, is a hot topic in
the IT world because of the potential for serious
economic benefits.
Server
virtualization enables multiple operating systems to
run on a single physical machine as virtual machines
(VMs). With server virtualization, you can consolidate
workloads across multiple underutilized
server machines onto a smaller number of machines.
Fewer physical machines can lead to reduced costs
through lower hardware, energy, and management
overhead, plus the creation of a more dynamic IT
infrastructure.
Windows Server
Hyper-V, the next-generation hypervisor-based server
virtualization technology, comes as a paert of Server
2008 Advanced Edition. Like all VM it allows you to
make the best use of your server hardware investments
by consolidating multiple server roles as separate
virtual machines running on a single physical machine.
You can also efficiently run multiple operating
systems - Windows, Suse Linux, and others – in
parallel on a single server.
With Hyper-V
and simple licensing policies, it's now easier than
ever to take advantage of the cost savings of
virtualization.
Applications
can be efficiently virtualized using Windows Server
2008 centralized application access technologies.
Terminal Services Gateway and Terminal Services
RemoteApp allow easy remote access to standard
Windows-based programs from anywhere by running them
on a terminal server instead of directly on a client
computer - without the need for a complicated virtual
private network (VPN).
The new Server
Core installation option of Windows Server 2008 allows
for installation of server roles with only the
necessary components and subsystems without a
graphical user interface. Fewer roles and features
means minimizing disk and service footprints while
reducing attack surfaces. It also enables your IT
staff to specialize according to the server roles they
need to support.
