HOW SERVICES VIRTUALIZATION
IS EATING THE WORLD
Technologies that network traffic to and from people,
machines and other objects that are on the telecom's
horizon today would be virtually unrecognizable
to the service providers of yesteryear. Top carriers
around the world are now taking steps towards
a software defined network (SDN) and network
function virtualization (NFV ) future. Yet where are
they on this path, and where is it going?
MAKING FAST PROGRESS
Stefan Kindt, head of cloud market development at
Nokia, states: "For NFV, carriers initially deployed
monolithic virtualized functions for the sake of
more efficient scaling, then they decomposed those
functions, but are now moving to micro services
deployed on virtual machines (VMs) and then micro
services without VMs, for ever-increasing agility and
scaling," Kindt comments. "Due to that, and pressures
coming from the surrounding competitive landscape,
carriers are beginning to focus on digitalizing
operations, because the complexity of today's
operations and network 'mesh on mesh' becomes
unmanageable when the high number of additional
NFV systems are meshed into the mixture."
Furthermore, says Kindt, SDN and NFV are now
extending beyond the datacenter: "Service providers
are extending these to remote locations with software
