36 NETWORKING The changing data centre David Trossell, CEO and CTO of Bridgeworks 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.
