Why are you doing this network project?
In the past you did not need to ask this question. The old network was unsupported, and the capacity was constraining the business. There were different questions of course; which vendor? where is capacity needed? Layer 2 or Layer 3? and wide area connectivity? In the last year this has changed. It is often now security or digital with examples such as:
The key thing is the next network has become a Board issue. Not because it will be expensive, but because it is a cyber-security or audit issue. Accountability might sit with the CIO, but the CRO is interested and has a direct line to the Board. In addition, the Board level drive for the business to become fully digital requires a “fit for purpose” platform to provide the ability for the digital teams to deploy new services.
Why has this changed?
I think it is a result of convergence of the most significant change in network architecture for 25 years and the threat environment, new threats driving the development of new countermeasures.
Software Defined Networking (SDN) is the technical change – the new architecture, with the software defined logical network built on a general-purpose underlay physical network. This approach relies on the ability to encrypt every flow on the fly. This needed the advances in processing power that are becoming commonplace. The ability to “virtualise” networks has been around for a while, but the business need to segregate traffic and to positively identify who is accessing the network is driven by the cyber threats. The need to provide the digital initiatives with a modern agile platform that will continue to support change, rather than constrain it, is also key.
But SDN brings so much more, including:
Whilst the cyber risk might be what has elevated requirement for investment it gives the CIO the opportunity to showcase the full value of building a true next-generation network.
