The Industrial Internet of Things (IIoT) is revolutionizing modern manufacturing capabilities. For years, smart organizations have benefited from analyzing large amounts of data at every step of their supply chains. Armed with these powerful insights, companies can optimize production and increase efficiency.

Edge computing, in particular, is experiencing a boom, as savvy manufacturers and industrial organizations dedicate on-premise computing resources to monitoring data and making critical production decisions in real-time. Investments are pouring into edge technology. Gartner, for example, predicts that 40 percent of enterprises will have a dedicated edge strategy by 2021, up drastically from the only 1 percent who felt this way last year.

However, edge computing also presents a number of new logistical challenges. Fortunately, manufacturers are establishing a reliable blueprint for IIoT success: implementing self-protecting, always available computing systems. Here is a breakdown of some of the most important considerations for operational technology professionals implementing edge technology.

IT/OT resource limitations

Companies expanding their IIoT presence must also consider which teams should hold ownership and responsibility for edge systems. As IIoT and edge computing skyrocket in popularity, traditional IT is being deployed at the operational level. This makes it difficult to distinguish information technology (IT) and operational technology (OT). As the two fields converge, OT professionals are being tasked with supporting and installing IT infrastructure outside of their typical skill sets, and vice versa.

IIoT pioneers must find ways to connect the two functions, as it is becoming more critical than ever to uncover combined IT/OT talent. Many companies are developing "hybrid OT" or "industrial IT" roles and hiring new employees. Others are investing in cross-functional training to expand current employee capabilities and encourage collaboration.

Either way, as companies begin to build a combined IT/OT perspective, limited on-premise IT staff and resources become a sizeable challenge. Adding to this difficulty, edge computing systems are typically located in remote areas that are difficult for staff to access. Under these considerations, self-protecting, continuously available systems are increasingly important, as they allow staff to focus on other projects. Investing in high-quality edge computing systems that OT teams can rely on creates a foundation for IIoT success.


Deploying OT security software upon edge technology is emerging as a cybersecurity best practice. In many cases, this provides an additional layer of security by locating threat detection resources on the edge of production networks, in close proximity to critical data.

Modern perceptions of cybersecurity threats tend to focus on data theft, but in reality, the downtime or decreased performance of essential tech infrastructure can affect entire supply chains. By dedicating infrastructure to on-premise data analysis, companies set themselves up to detect any potential anomalies in real time. OT professionals can rely on insights from the edge to quickly analyze and respond to any anomalies in system performance that come from malware attacks. Minimizing the time required to respond to potential risks helps ensure key tech infrastructure performs at a high level.

Analyzing security risks in real time with edge computing helps OT professionals keep their production cycles running smoothly and efficiently, protecting the cycles from decreased infrastructure performance. OT teams operating edge technology should conduct regular cybersecurity audits to establish clear security baselines and protect themselves from risk.

Difficult environments and virtualization

OT professionals implementing new edge products must navigate different automation environments, many of which present challenging layouts. Today's factory floors, particularly those exploring IIoT automation, are problematic to navigate. Many are lined with separate networks for process control and plant management, in addition to hosting several unique servers dedicated to single applications. As manufacturing environments change, adding additional servers for each new application can drain computing resources.

Virtualizing servers onto a single edge platform allows OT professionals to build a flexible foundation for IIoT success in these difficult environments. Centralizing resources through virtualization can reduce server sprawl and open new space at the edge of the network. Virtualization onto a single server can also make systems easier to manage, repair, and scale, all at a lower cost.

Of course, organizing multiple applications on one virtualized platform demands additional attention to server reliability. If a virtualized server shuts down or underperforms, so will the various production applications and functions it supports. OT professionals should take all necessary measures to make their virtualized servers fault tolerant and always available.

As rapidly improving IIoT and edge computing capabilities present new opportunities, they also present an array of new talent, infrastructure, and security considerations. To ensure effective computing success at the edge, OT departments should prioritize highly secure edge computing systems with a hybrid OT staff.
