Re: agile networking
I think you have hit the nail on the head -- without the Cloud, data analytics would be very difficult and without data analytics it is difficult to create value that drives the functionality of a device higher. And without a network capable of handling the data needs, value created cannot be implemented.
It is this interlinked nature of the IoT that makes it extremely interesting. Whether, networks are to become vastly more centralized or decentralized depends a lot on the type of products that will constitute the majority of those 50 billion connections. Either way, the network is a good place to understand the changes that are on their way.
SDN is important in the network to enable network orchestration, etc. I feel that SDN is also important on the business side, as it enables the kind of long term relationships between data service providers and device producers that will be needed.
