The impact of networking costs
and how the industry is evolving to
make the impossible, possible
Mattias Fridström, Chief Evangelist for Telia Carrier says
lower networking hardware costs are forcing data centres
and metro networks to fundamentally change how they
conduct their business. “Any location with fibre can now
become a data centre, opening up new opportunities for
designing, managing, and operating cloud and on-demand
computing resources,” he comments.
In the past, the networking hardware costs were
extremely prohibitive, and so connecting different
data centres to each was often an expensive exercise.
Organisations such as Google, Facebook, Amazon and
Intel have been at the forefront of the software designed
revolution in computing, and they’re now moving into the
networking arena with SDN and SD-WAN. This is displacing
the traditional costly propriety silicon purveyors of network
equipment. With lower costs and higher speed connections,
the dynamics are changing. In turn, this is transforming the
costs associated with data centres, public, hybrid and private
clouds – making them more accessible and more affordable.
Restricted capacity
For years the network capacity inside the data centre has
been restricted by their underlying technology, but with the
advent of new silicon and signal processing the costs have
been pushed down. At the same time network performance
has increased inside the data centre. In the past this used
to be restricted to 10Gb/s connectivity, but they now
commonly have 100GB/s or higher at their disposal. So,
lower costs and higher performance have become the new
norm. This means it’s now possible to exploit this new high
capacity WAN connectivity.
