While most observers agree that Edge Computing is a paradigm shift in computing. There is no singular definition of Edge Computing that has gained consensus. IEEE defines Edge Computing as something that places applications, data, and processing at the logical extremes of a network instead of centralizing them. Linux Foundation says something similar - “The delivery of computing capabilities to the logical extremes of a network in order to enhance the performance, operating expense, and reliability of applications and Services.”

While most observers agree that Edge Computing is a paradigm shift in computing. There is no singular definition of Edge Computing that has gained consensus. IEEE defines Edge Computing as something that places applications, data, and processing at the logical extremes of a network instead of centralizing them. Linux Foundation says something similar - “The delivery of computing capabilities to the logical extremes of a network in order to enhance the performance, operating expense, and reliability of applications and Services.”

But what are the “logical extremes” of the network? In most instances, they're the end user devices – smartphones, sensors, automobiles, health monitors, etc. From a foothold Computing perspective, the situation (not necessarily the physical location) is defined by the task at hand and the way one gets capabilities to the node that needs it during a most cost effective and scalable manner. For e.g.

• If one is trying to find location data for a couple of hundred devices at an equivalent instance in a local district, the bottom station is ideally most suited to possess that information that can be dispersed to the entity that needs it, therefore the base station is that the edge up this instance.
• For a drone that's collecting images in real-time on a pipeline and is trying to determine if there are noticeable changes, the drone itself is the edge device which can do that determination.
• In some instances, the vehicle traffic data must be aggregated to predict congestion in cities. In such scenarios, the aggregation layer is that the edge.
• In healthcare use cases, counting on the state of the appliance and therefore the task supply-chain, the sting could vary from being at the device on the patient (like smart watch or the guts monitor), at the RAN (in operator’s network), at the local hospital chain (that is processing the info from multiple patients) or at data aggregation point (that is watching the national data streaming in).
• In the case of face recognition based security systems at schools, using facial vectors for authentication are often done employing a local small cell or access point (in which case which will be the edge) while if you're trying to match a face to a wanted database, typically, you'll roll in the hay with the assistance of aggregation nodes or centralized cloud intrinsically the sting moves back within the network. However, if you are doing a recognition to validate the user for a tool, the device itself is performing all the computations and authentication and becomes the sting.

Market Forces Enabling Edge Computing

There is a singular phase of technology evolution when many symbiotic breakthroughs and generational changes are happening at an equivalent time. The wireless industry is beginning its 5G cycle that's bringing during a new set of capabilities to the market like enhanced broadband, lower latency, support for denser IoT deployments, network slicing, tighter security, and far more. The sensors are being miniaturized and becoming embedded into everyday things. The computing platform is available to those sensors for not only processing basic data emanating from the sensors but also to the AI algorithms which will add up the info in real-time.

Finally, the new genre of applications and services are emerging that need a way more distributed approach to information distribution and processing.

Over the past few years, the industry have been making tremendous progress on several fronts:

Hardware: Sensors became less expensive and smaller to the purpose that are putting a sensor in almost everything.

Data: the supply of sensors at the sting has meant that the quantity of knowledge available to derive intelligence has grown manifold.

Software: Finally, the industry has emerged out of the AI winters of the past to really make AI a programmable component of the software stack during a way which will ingest data and automate functions during a rapid manner. The engine can self-correct and self-learn as more data becomes available. Additionally, the character of the wireless networks is changing. From relying totally on the macro network of base stations across the country to now densifying the network with the assistance of small cells and access points. 5G will further accelerate densification of the network with the amount of small cells quite double within the next five years. This suggests that the first network touch point for the device is going to be much closer than it used to be. Smartphone itself has changed tremendously. The newest iPhone is capable of 5 teraflops which is quite what a cloud server was ready to do only five years ago. Smartphones will have the potential of acting as a foothold device to other smartphones for location, content, and processing.

One of the foremost significant challenges for the subsequent decade are going to be how the networks manage data traffic. Mobile data traffic is exploding worldwide. India’s Jio has been clocking 10 GB/sub/month for over 250M subscribers. Finland’s DNA announced that the data consumption on its network went past 20 GB/sub/month. T-Mobile USA also went past 10 GB/sub/month because it is the fastest growing network within the US. Overall data traffic is predicted to quite quadruple over subsequent five years. Furthermore, with automobiles coming onto the network, the quantity of traffic per vehicle is going to explode.

Practically every vehicle beginning in the factories will have an embedded cellular modem. The info demand for vehicle operation, entertainment, and communications within the vehicle goes to travel up dramatically. All this requires effective management of the info traffic flows especially video which can continue its domination into the 5G era. Edge will play a big role in processing data at the sting for not only offloading but also extracting intelligence and meaning out of data.
