With the new year comes resolutions and predictions for what lies ahead. Having been a pioneer in Edge Computing since 2014, we've helped many companies with their digital transformation initiatives and have completed over 100 commercial edge computing engagements. We have seen first hand how the market has been maturing and the many use cases that exist.
In 2018, Edge Computing reached an inflection point of digital transformation. We're now seeing leading industrial players moving from IIoT pilots into full-scale enterprise deployments. With the increased adoption of real-time industrial edge intelligence, industrials will benefit from significant operating efficiencies, maximum asset performance and improved process improvements.
As we look forward into 2019, we wanted to share with you our predictions of the market and trends as we see companies increase their adoption of real-time edge intelligence.
1. Survival of the smallest. IIoT analytics and ML companies will be heavily measured on how much they can deliver in how little compute.
As IIoT projects extend beyond cloud-centric approaches, the next step in the evolution of artificial intelligence and IIoT will address the need to convert algorithms to work at the edge in a dramatically smaller footprint. According to Gartner, within the next four years, 75% of enterprise-generated data will be processed at the edge (versus the cloud), up from <10% today. The move to the edge will be driven not only by the vast increase in data, but also the need for higher fidelity analysis, lower latency requirements, security issues and huge cost advantages.
While the cloud is a good place to store data and train machine learning models, it cannot deliver high fidelity real-time streaming data analysis. In contrast, edge technology can analyze all raw data and deliver the highest-fidelity analytics, and increase the likelihood of detecting anomalies, enabling immediate reaction. A test of success will be the amount of “power” or compute capability that can be achieved in the smallest footprint possible.
2. The market understands "real" versus "fake" edge solutions.
As with all hot new technologies, the market has run away with the term “edge computing” without clear boundaries around what it constitutes in IIoT deployments. “Fake” edge solutions claim they can process data at the edge, but really rely on sending data back to the cloud for batch or micro batch processing. When reading about edge computing, the fakes are recognized as those without a complex event processor (CEP), which means latency is higher and the data remains “dirty,” making analytics much less accurate and machine learning (ML) models are significantly compromised.
“Real” edge intelligence starts with a hyper-efficient CEP that cleanses, normalizes, filters, contextualizes and aligns “dirty” or raw streaming industrial data as it’s produced. In addition, a “real” edge solution includes integrated ML and AI capabilities, all embedded into the smallest (and largest) compute footprints. The CEP function should enable real-time, actionable analytics onsite at the industrial edge, with a user experience optimized for fast remediation by operational technology (OT) personnel. It also prepares the data for optimal ML/AI performance, generating the highest quality predictive insights to drive asset performance and process improvements.
Real edge intelligence can yield enormous cost savings, as well as improved efficiencies and data insights for industrial organizations looking to embark on a true path toward digital transformation.
3. ML/AI models get skinny with edgification.
Moving machine learning (ML) to the edge is not simply a matter of changing where the processing happens. The majority of ML models in use today were designed with the assumption of cloud computing capacity, run time and compute. Since these assumptions do not hold true at the edge, ML models must be adapted for the new environment. In other words, they need to be “edge-ified”. In 2019, “real edge” solutions will enable relocating the data pre- and post-processing from the ML models to a complex event processor, shrinking them by up to 80% and enabling the models to be pushed much closer to the data source. This process is called edgification, which will drive adoption of more powerful edge computing and IIoT applications overall.
4. Closed-loop edge to cloud machine learning will become a true operational solution
As machine learning (ML) and AI algorithms become “edgified” for use close to sensors or within IoT gateways or other industrial compute options, new best practices will emerge on how to train and further iterate on these models. What industrial organizations will find is that edge devices generating analytics on live streaming data (including audio and video) should regularly send insights back to the cloud, but only those that represent anomalous activity warranting a shift in the core algorithms. These edge insights enhance the model, significantly improving its predictive capabilities. The tuned models are then pushed back to the end in a constant closed loop, reacting quickly to changing conditions and specifications, and generating much higher quality predictive insights to improve asset performance and process improvements.
5. Production IIoT applications will go into implementation only with edge computing solutions supporting multi- and hybrid-cloud deployments.
Hybrid- and multi-cloud solutions will dominate the industrial IIoT deployments – a recent report found that the hybrid-cloud market will reach $97.64B USD by 2023. As industrial organizations look to bring multi-cloud environments together to provide a more cost effective approaches and flexibility, it will be important for edge solutions to be cloud agnostic. Vendor-exclusive solutions will likely begin to fall by the wayside as companies look for more flexibility and freedom of choice when building their edge-to-cloud environments. Google, AWS, Microsoft, C3IoT, Uptake and other leading cloud providers will establish more collaborative partnerships with edge computing companies to help businesses as they continue to improve and expand their offerings.
6. IoT video and audio sensors take off, driving the need for deep learning at the edge.
There is industry-wide excitement about the capabilities that audio and video sensors can bring to the IIoT. Edge computing technology can play an important role in the further deployment of audio and video data in commercial and industrial IoT systems. The fusing of asset data with audio and video analytics will allow for faster and more accurate device and machine maintenance (including updates on systems health and more), and a whole host of new innovative applications. One such example of the video analytics is the use of flare monitoring at oil and gas operations to track environmental compliance and flare state remotely for large volumes of flare stack towers.
7. Predictive maintenance gives way to prescriptive maintenance.
One of the big promises IIoT edge solutions deliver is predictive maintenance, offering insight into what is likely to happen to a connected asset (like manufacturing equipment or an oil rig) in the future. While many organizations still lag in implementing predictive maintenance as a first step, even more advanced technology will be available to early adopters in 2019.
Prescriptive maintenance is a step forward to enable businesses to not only predict problems, but also produce outcome-focused recommendations for operations and maintenance using data analytics.
For example, elevator manufacturers want to put an end to routine problems, such as friction in elevator doors. As part of this effort, they partner with Foghorn to create a predictive maintenance solution. By analyzing sensor data at the source, they can now determine maintenance needs well in advance, without the cost, latency, security and other issues associated with transfer of large amounts of data outside of the building. Thus, it can schedule service before anomalies impact performance in a highly efficient manner. As prescriptive maintenance becomes available, before the manufacturers roll a truck to provide maintenance on an elevator, they will have data available to suggest areas most likely to need repairs and have verified the repair staff person the expertise, tools and parts available for the repair.
