FEATURE: CLOUD MANAGEMENT
to manage. Static policies are not
able to follow the dynamics of
usage, the traffic matrix is more
meshed and complex.
• While network performance can
be controlled and optimised onpremise, guaranteeing performance
for mobile users and/or offpremise applications is extremely
challenging.
• Holistic visibility on the traffic and
the network becomes a distributed
problem and requires more
instrumentation devices than ever.
• Managing SLAs delivered by the
multiple network service providers is
getting more complex. Visibility on the
performance delivered by off-premise
cloud service providers is a new
problem without a practical solution.
Over the past few years, a novel
architecture has emerged to solve

similar problems at the data centre
level: Software Defined Networking
(SDN). SDN provides multiple benefits
that can be summarised by having
a network that is able to support the
most modern data centre workloads
and create Opex and Capex savings at
the same time.
