Five predictions for edge computing in 2022 include a proliferation of artificial intelligence (AI) and machine learning at the IOT edge and edge-cloud architectures as the norm.
IOTech’s has reported a series of 2022 predictions are related to technology advancements, architectures and impact to industries.

The company believes that the effect of edge computing on blockchain and other digital ledger technologies will become clearer in a few years. Similarly, 5G’s impact on edge computing is still too early to predict.

“This past year, we’ve seen edge computing emerge from pilot programs to deployments,” said Jim White, CTO, IOTech. “We believe 2022 will be the year that edge computing is fully integrated into the architecture of every major industrial IoT system.”

Prediction 1: There will be pervasive adoption of AI/ML at the edge

The new status quo is that edge systems will incorporate AI and machine learning. Simple rules engines and edge analytics are already at the edge. Today, organizations demand more intelligence at the edge. The raw compute to run AI/ML at the edge was a prohibiting factor, but this is no longer the case.

While training ML systems will largely occur in the cloud or in the enterprise, ML models running on lighter AI runtime engines at the edge are more common place and will soon be the norm.

Visual inference has been a leading use case, but other AI/ML solutions are soon to follow. Edge platform providers will play a key role in developing solutions that can easily integrate AI/ML technologies.

Prediction 2: Hybrid edge-cloud architectures will be the norm

It’s not edge compute “or” cloud compute, it’s a case of “and”. Organizations are finding that processing edge data needs to be performed at the edge and in the cloud or enterprise. Although initially there was much excitement related to the cloud providers reaching down to the edge, the reality is that there are significant challenges in moving all edge data to the cloud and performing all the processing in the cloud.

The cost of data transport, latency issues and security/data privacy concerns are among the chief challenges. Likewise, the raw processing power of the edge and ability to do deeper exploration of the edge data over longer periods of time for better insights means edge computing alone is not a solution. Solutions must allow for the right processing at the right levels, and this calls for hybrid edge-cloud architectures.

Prediction 3: The industrial sector emerges from edge/IOT research mode

The industrial sector is becoming focused and organized in its effort to offer new solutions at the IoT edge. Businesses in manufacturing, building automation, and smart energy are in full “build” or “buy” mode for IoT edge solutions.

Many large industrial sector businesses are fully committing to grow their edge/IoT products and strategy. Buy mode leads when companies need to accelerate digital transformation.

Prediction 4: Customers will demand solutions rather than pieces/parts

Companies looking to benefit from edge/IoT technology are looking for more fully integrated solutions. They want immediate tangible business outcomes and are not interested in receiving a bucket of technology parts that they then have to pull together themselves.

For system integrators, it means developing the right technology partnerships to pre-assemble and deliver complete solutions to customers. Integrators will naturally gravitate to edge products that are inherently more open and flexible as these will be easier to integrate and adapt to more use cases.

Prediction 5: Realization that K8s is not enough edge management

Organizations deploying and orchestrating IoT/edge applications are discovering that Kubernetes is not always a fit in resource constrained edge environments. Furthermore, K8s only addresses part of the edge management need. There is more to edge management than managing/monitoring containers.
An edge management solution must deal with preparing, managing, and monitoring the host edge nodes, allow for rapid configuration changes, and even assist in sensor/device onboarding. K8s will be part of some edge management solutions – where there are more resources or smaller K8s solutions (K3s as an example) can be applied.
However, the thin, resource constrained, network constrained, latency concerned, sometimes non-containerized, OT device-touching environments demand alternative and more complete edge management solutions.

In addition to these predictions, the company also offered these insights:

Traditional IT hardware OEMs will need to develop edge/IOT strategies

Edge solutions don’t start with the selection of IT hardware. They start by addressing the challenge that is being solved or the outcome that is needed and then building the right system to meet these requirements. As the IoT edge becomes ubiquitous, all layers of the architecture need to be an effective part of the solution. IT hardware OEM vendors need to ensure they have a vision and strategy in the edge/IOT space or risk becoming irrelevant or a commodity to edge customers.

Digital twin standards are needed to ensure pace of innovation.

The current lack of a digital twin standard is hampering adoption and requiring organizations to roll their own interoperability solutions or be locked into a single provider’s implementation. With digital twin technology increasingly becoming a sought-after part of the IoT solution, a standard is the next logical and crucial step to drive innovation.

The use of digital ledger technology (i.e., block chain) will start to grow.

The need to deliver data from the edge with trust and confidence–and to be able to govern its ownership and distribution given the distributed nature of edge data—clearly points to the use of block chain and other digital ledger technology. At some point in the not-so-distant future, organizations implementing edge solutions will want to monetize edge data and will look to properly protect, label, distribute and score edge data.

Noise level for edge and 5G will continue

From an edge platform perspective, 5G provides a bigger, stronger, less latent pipe between the edge and the enterprise or cloud. Because it can reduce latency, 5G can allow more processing to occur in the cloud.

5G could become more interesting to edge/IoT solution providers as telecos work toward implementation of private (or semi-private) 5G installations in factories, stores, campus, etc. that allow more “things” to be connected but in a secure and isolated way.

COVID sped up challenges that were already exhibiting

Supply chain issues and human resources challenges were already beginning to be exhibited prior to the pandemic. COVID accelerated and heightened these issues for organizations. As businesses and industries emerge from the pandemic, 2022 cannot be a return to normal.

Companies must innovate and use technology to address the aforementioned challenges. Therefore, IOT edge adoption will accelerate. It will be the year that companies transition from research and pilot programs to launches and deployments at scale.

Partnership with Google Cloud to provide integrated Edge-Cloud solutions at scale

IOTech’s IoT platforms, Edge Xpert and Edge XRT enable Google Cloud customers to extract and process data from a broad range of OT devices at the edge. IOTech announced it is expanding its partnership with Google Cloud to offer smart and integrated edge-cloud solutions for enterprise companies. With this partnership, industrial users including manufacturing, building automation, and smart energy can now deploy smart, no-code and integrated edge-cloud solutions at scale.

This expanded partnership will impact industrial IoT deployments which come with certain challenges including OT/IT integration. The northbound communication protocol to Google Cloud is typically MQTT or REST while the southbound communication protocols include Modbus, BACnet, Ethernet/IP, S7, OPC-UA and many more. Other challenges industrial users face include the ability to extract data from old, and legacy IoT devices and the ability to control what data specifically is sent to Google Cloud, mainly for security, latency and/or cost reasons. Edge computing capabilities and features therefore play an increasingly important role in industrial IoT.

The partnership allows the industrial user to deploy a smart, no-code and integrated edge-cloud solution at scale. IOTech’s Edge Xpert typically resides on the edge gateway or server level while Edge XRT can reside on legacy or resource-constrained hardware such as MCUs and PLCs, typically found at the far edge.

Both platforms come with 20 plus OT connectors including Modbus, BACnet, Ethernet/IP, S7, OPC-UA, and many more. The platforms also include an SDK making it easy for customers to build new OT connectors, if required. Seamless data integration with Google Cloud is provided as standard.

“IOTech is excited to be a Google Cloud Edge ISV partner. The integrated edge-cloud solution allows for fast deployments, reducing the time to value. Adding an OT device is enabled through simple configuration and no coding skills are required,” said Keith Steele, CEO of IOTech Systems.
