Sensors & Edge computing
For businesses, the most important benefit of the IoT will be the data generated by billions of new smart sensors and devices. The “Internet of Everything” — all of the people and things connected to the internet — will generate 507.5 zettabytes (1 zettabyte = 1 trillion gigabytes) of data by 2019, according to Cisco. Managing, sifting through, and analysing so much data will be a massive challenge for organisations. But that data analysis will be essential if IoT initiatives are going to provide the insights to drive greater productivity and revenues.
Right now, most of this data management and analysis is performed in the cloud or enterprise data centers. However, several IoT technology providers are promoting a different model called edge computing, or “fog computing,” for the IoT. In an edge computing model, sensors and connected devices transmit data to a nearby edge computing device, such as a gateway device (a networking device like a switch or router) that processes or analyses the data, instead of sending it back to the cloud or a remote data center.
A recent report from BI Intelligence looks at the market for edge computing solutions tied to the IoT and explains the specific benefits and challenges around using edge computing for enterprise IoT data storage and processing. It also examines which industries we expect to lead in adopting edge computing and how the technology could increase productivity and efficiency in these particular sectors.
Here are some of the key takeaways:
- Edge computing provides a means to collect and process data at local computing devices rather than in the cloud or a remote data center.
- We estimate that 5.6 billion IoT devices owned by enterprises and governments will utilise edge computing for data collection and processing in 2020.
- Edge computing is often better suited for collecting and processing data from IoT devices than the cloud. Edge computing can be accomplished using gateway networking devices, industrial PCs, or micro data centers.
- The edge computing model is uniquely well suited to IoT applications because of several key benefits, including near real-time analysis of data, lower costs related to operations and data management, reduced data sent back to the cloud (and, therefore, less constricted networks), and the assurance that other IT assets will remain operational even when one device malfunctions.
- We expect that the manufacturing, utilities, energy, and transportation industries will be the fastest to adopt the technology. These industries will be followed by smart cities, agriculture, healthcare and retail.
- Deploying edge computing for IoT devices can be a complicated task, but emerging standards could help simplify deployments.
