What is edge computing? Here’s why the edge matters and where it’s headed


Edge computing can reduce network latency, lower the exposure of data to the network and, in some cases, reduces costs by offloading processing to end users’ devices. Although centralized data centers are important to cloud computing infrastructure in the current times, there lies a bigger problem that they cause. A single data center can consume the equivalent electricity of for 50,000 homes. With Edge Computing, operations technology teams are able to provide critical data processing at the very edge of a network rather than in the cloud or via a centralized data warehouse. Such real-time data processing can significantly improve the way many of these organizations run their business, and in doing so, deliver many powerful new benefits.

If you have any questions about edge computing vs cloud computing that are not answered in this article, share them in the comments section below. While these devices are akin to PCs, they are not regular computing devices designed to perform multiple functions. These specialized computing devices are intelligent and respond to particular machines in a specific way. However, this specialization becomes a drawback for edge computing in certain industries that require immediate responses.

We’d need massive fiber optic pipes to supply the necessary backhaul, but the revenue from edge computing services could conceivably fund their construction, enabling it to pay for itself. Applications may be expedited when their processors are stationed closer to where the data is collected. This is especially true for applications for logistics and large-scale manufacturing, as well as for the Internet of Things where sensors or data collecting devices are numerous and highly distributed.

The technology’s high bandwidth, low latency potential could also make remote surgical procedures significantly more viable by reducing the delay between physician input and robotic surgical implements considerably. AT&T hopes to deploy its MEC edge computing solution to VA facilities across the U.S. upon completion of the trial, which could benefit more than 9M veterans nationwide. Verizon is also developing 5G-enabled edge computing technologies at its 5G Lab in Cambridge, MA, that minimize latency between the surgeon and robotic operator.

But it’s at the edge where each store micro-adjusts the initial forecast with specific on-site, real-time data from their kitchen and point-of-sale systems. Using compute at the edge is how they can make sure everyone’s fries are crispy, whether it’s a slow afternoon or a crush of families after a little league game. Traditional private facilities stifle growth by locking businesses into projections of their future computing requirements. Insufficient computing capabilities may prevent them from capitalizing on opportunities if corporate development exceeds expectations. Building a separate data center is an expensive proposition, making future planning much more challenging. Aside from the significant upfront building expenses and continuous upkeep, there’s also the issue of future requirements.

The device can be used to perform tasks that would otherwise require a lot of effort or time on their part. Consumers can use their devices more conveniently, making them more productive. Another way edge computing reduces bandwidth consumption is by reducing the number of hops from the server to a user’s device. This technique transfers data packets directly from one device butterfly rib tattoos to another without going through an intermediate server. Edge computing reduces latency for end users by moving computation work to local devices, such as smartphones and laptops, rather than offloading the work to the cloud. In addition to improving agility and cost-effectiveness, edge computing also enables users to use their devices as a trusted compute resource at scale.

It’s also planes, trains, and other forms of transportation — driverless or not. One of the most obvious potential applications of edge computing technology is across transportation — more specifically, autonomous vehicles. Hewlett Packard Enterprise said in 2018 that it would invest $4B in edge computing over the next 4 years. HPE’s Edgeline Converged Edge Systems is targeted at industrial partners that desire data center-level computing power while often operating in remote conditions.

It can help prevent hackers from gaining access or stealing your data as you’re not storing data in one central location. This aspect of edge computing is improving social sustainability by improving the security of personal data. To save money and cut carbon emissions, you can use the servers, switches, storage, and software that are already in use. It’s not necessary to spend time looking for new technology or building entirely new infrastructure.

Edge computing is playing a major role in transforming the way of handling, processing, and transferring the data to million IoT devices across the world. This article provides an overview of the different aspects of edge computing supporting IoT devices. The comparison between edge computing and cloud computing for IoT devices based on various aspects has also been discussed to provide better insights. The article also brings into focus the IoT functionality support provided by edge computing. Finally, we introduce the pertinent issues and new research directions, which require additional investigations for edge computing.

Fog.But the choice of compute and storage deployment isn’t limited to the cloud or the edge. A cloud data center might be too far away, but the edge deployment might simply be too resource-limited, or physically scattered or distributed, to make strict edge computing practical. Fog computing typically takes a step back and puts compute and storage resources “within” the data, but not necessarily “at” the data.
