Utility computing aggregates disparate
systems into a single, centrally managed pool
of resources that offers unified control,
freedom from physical configuration, resource
sharing, and resource isolation.
To provide these features, the authors
propose a software-based utility data center
that virtualizes server, network, and storage
resources. SoftUDC's main underlying characteristic
is careful virtualization of servers, networking,
and storage. With SoftUDC, administrators
can deploy applications and modify their
environment without physically rewiring
servers, which facilitates sharing of physical
resources while maintaining full isolation.
