Considering heightened security threats, data proliferation and the upsurge in mobility, Edge Computing seems a natural solution to today’s infrastructure limitations. With Equinix predictions of organisations operating at the digital edge realising $2 trillion in extra benefits over the next five years, there are a number of reasons – from enhanced data processing to more robust security – why many organisations are looking towards the Edge:
It boosts network capacity and speed
Internet-enabled devices add strain on the cloud – with datacentres often based hundreds or thousands of miles from the end-user, the sheer volume of data being processed can burden operations, causing a lag and reducing productivity. By processing data at the edge of a network, where activity is physically taking place, businesses enjoy a reduced latency and improved service quality. Data bottle-necks reduce, and companies can be much more selective over what they do send to the cloud. This frees up cloud resources to focus on heavier tasks, while simultaneously enabling end-point applications and processing to occur in real-time for increased mobile productivity. As 5G comes to the fore, with a projected subscription base of half a billion by 2022, the significant speed increase it will provide will drive mobile data usage to new levels.
It embraces the rise of IoT
A result of this is that, with the Internet of Things (IoT) coming to the fore, an Edge Computing architecture enables organisations to embrace these technologies without worrying about a data overload. IDC predicts global IoT spending to reach $1.4 trillion by 2021, bringing with it a significant data swell – Cisco forecasts 14.1 zettabytes (ZB) of data present in the cloud in 2020, compared to only 3.9 ZB in 2015. An Edge-centric approach will be required to handle and maximise such data levels.
It keeps data distanced for extra security
80 per cent of mobile device data is encrypted – far more than corporate data, which is generally more sensitive. With processing taking place at the Edge and between local end-points, a higher percentage of data will be encrypted before it’s sent to the network’s core. Malware, compromised files and hack attempts are therefore far less likely to penetrate the central IT infrastructure, with organisations instead having a higher chance of recognising such threats at the Edge.
