In recent years, there has been a shift in how content delivery, IoT, and emerging information and operational technology applications impose stringent requirements on networks. Latency and bandwidth requirements of today’s applications demand further optimization of network transport and data processing at or close to end devices – The Edge.

Until recently, technologists have viewed cloud computing as the prevailing choice to control connected things and data while providing intelligence based on the data. Response time and network load are now proving too high for cloud-based solutions. Distributing intelligence at the edge stops the need for traffic data to travel deeper into the network. Sending data back to the cloud over a mobile network and waiting for a response, may cause unacceptable delays. Intelligence must be localized to work with the data as fast as it hits the network. Intelligence at the edge will decrease delays and increase the experience.

This brings up the question: How to define what or where the edge is. In some ways, it is a floating target. Some refer to the edge as the point where a service is produced and consumed or at the natural point between where data is handed to something or someone different. An IoT server crunching the data for all collection points has its edge in the actual server. An ISP collecting content data from a carrier often has its edge in a larger data center within a major city. Take the car industry as an example. A manufacturer needs to conduct test drives in winter conditions where it is winter and where in the off-season, winter conditions can be created at an affordable cost. To make the best analysis of a test drive within a short period of time and to re-test without losing too much time, the manufacturer will need excessive compute power very close to the test facility. It would be far too costly and time consuming to send this data back to the corporate headquarters or production plant. Instead, it would be ideal to locate the server very close to the test drive facilities, thus putting the edge just around the corner.

IoT, storage and when the edge is not the answer

There are examples where edge computing really is not the answer. For example, if you need to analyze vast amounts of data collected over a large geographical area, it is only when you have all this data in a single point that you can draw the conclusions needed. A centrally-located mega data center based on cheap, green power, stable climate and experienced data center experts would fit your needs perfectly.

The IoT trend is naturally also driving the edge further out from the main centers. For a farmer collecting loads of data from hundreds of devices checking the soil, the water quality and the weather that he/she needs at the farm, a server in a very close by edge data center would fit their needs. There would be no need to send this data long distances since the purpose is to use it at the farm. Now, if you add neighboring farms to the mix with the same need that want to compare data, suddenly there is a need to connect to more centrally located data centers.

Applications that have a natural storage need are another example that does not really need to be at the edge. Companies that keep records of transactions or store larger files of data should not consider the edge. Here, the need is again to find the most ideal data center location with a vast amount of cheap, green power combined with a good climate and experienced data center staff. Around the globe, there are places in the Nordics and some part of the Pacific Northwest in the U.S. that possess these qualities.

To ensure distributed intelligence, data center-style facilities should be closer to where the data is generated. “Data center-style” could be anything from a server inside a mobile base station to a complete data center with hundreds of racks and a vast amount of power. To connect all these data centers - now distributed further away from the normal hubs of the largest cities - to places where fewer people live is a challenge for an operator and especially an international carrier. Even the smallest data center at the edge of the network needs to be connected to the core to reach its full potential. What we are likely to see is a multi-faceted infrastructure where learning happens on the edge of the network and in the cloud. Reaping value from both edge and cloud, thus enabling distributed intelligence. This implies providing intelligence by ensuring information is closer to the devices. Therefore, a combination of edge and core is essential to be successful.

There’s a certain type of person who gets a little bit too excited about networks. Mattias is that guy. If he had a tattoo, it would be of a network. His knowledge is mind-boggling and his passion irrepressible - no one makes connectivity come alive like Mattias.

He offers deep insights into the networked economy. What are the challenges of tomorrow for network providers? How can we meet ever-increasing traffic demand and customer quality expectations within the same cost frame?

Mattias holds an MSc in Electrical Engineering from the University of Wollongong, Australia. Since joining Telia in 1996, he has worked in a number of senior roles within Telia Carrier and most recently as CTO. Since July 2016 he has been Telia Carrier’s Chief Evangelist.

Mattias’ passion isn’t limited to networks: He has played golf professionally and competed on a national level in football and innebandy. Although he has a reputation when it comes to sports as being the “worst loser at Telia Carrier”, he is working hard to overcome this – by not losing to anyone. At anything. Ever.
