Virtual Private Server (VPS)
is a
virtual machine sold as a
service by an
Internet hosting service. A
VPS
runs its own copy of
an
operating system, and customers have
superuser-level access
to that
operating system instance, so they can
install almost
any required
software that runs on their
virtualized OS
. For many purposes they are
functionally equivalent to a
dedicated physical server, and being software
defined are able to be
much more easily created and configured. They are priced
much
lower than an
equivalent physical server, but as they share the underlying
physical hardware with other
VPSs
,
performance may be lower, and
may depend on the
workload of
other instances on the same hardware node.
