The early days of Edge Computing will influence how developers and enterprises adapt to new ways of designing applications and services. There are several use cases we've discussed throughout the paper, but we'll highlight a few in additional detail to offer you a way of the performance gains from Edge Computing and why it matters. In this section will highlight three important areas of imaging, website content delivery, and autonomous operations.
Imaging
It is accepted wisdom that responsiveness of applications and services features a direct correlation to improvement in consumer behavior, increase in commerce, and a stepchange in revenues. As history of the tech industry of the last twenty years indicates, even slight upgrades can have a big impact on user engagement. Edge computing will play a central role in providing significant uplift in improving end-to-end latency for not only current set of applications and services but more importantly the upcoming new breed of services and applications which will define them like computer game, Multiplayer gaming, face recognition, Enhanced Video Streaming, Automotive, Robotics, etc.
Measurement of response times for AR, face recognition , and Video across cloudlets (Edge Computing cloud) vs. traditional cloud (Amazon Web Services) indicates there's a significant advantage of using near-edge cloud services compared to the cloud that's geographically dispersed. Data clearly shows a marked improvement in reaction time employing a cloudlet approach. Edge isn't only great for response times but also battery operation on the devices as indicated in Figure 6 across two applications. face recognition is an application that performs well if the comparison of the facial vectors is completed at the sting vs. the cloud. Similarly, the Augmented Reality applications and services need lower latency for optimal user experience. If the video frames aren’t formed in time, the user can get dizzy and it'll leave a nasty taste.
Content Delivery
Web has become the central pillar of commerce. The revenue created are often directly correlated to the response times of internet sites and applications especially during busy holiday season and at some point commerce events like Black Friday and Cyber Monday. The science behind website performance and conversions, abandonment rates, consumer sales, repeat traffic, and eventually revenue is well studied over the last decade. Enterprises have deployed different techniques to hurry up the response times, be it the location design, data centers, or CDNs (content delivery networks). Over 74% of the mobile users will abandon a site after waiting 5 seconds for a page to load. Each second shaved features a direct impact on user experience and therefore the life value of that customer.
In fact, we might argue that the conversation within the Connected Intelligence Era has moved from response in seconds to content delivery in milliseconds, esp. For the millennials. The dimensions of a mean webpage has increased 10x over the last eight years so it's necessary to develop new techniques to enhance responsiveness.
