Leading experts debate how virtualization and
clouds impact network service architectures.
By mache cReeGeR
the geneRAL It community is just beginning to digest
how the advent of virtual machines and cloud
computing are changing their world. These new
technologies promise to make applications more
portable and increase the opportunity for more
flexibility and efficiency in both on-premise and
outsourced support infrastructures. Virtualization can break
long-standing linkages between
applications and their supporting physical devices, however.
Before data-center managers can take
advantage of these new opportunities,
they must have a better understanding
of service infrastructure requirements
and their linkages to applications.
In this ACM CTO Roundtable, leading providers and users of network
virtualization technologies discuss
how virtualization and clouds impact
network service architectures, both in
their abilities to move legacy applications to more flexible and efficient virtualized environments and to enable
new types of network functionality.
