On a basic level, IoT is a technology using sensors to collect and transmit important data (pressure, IR, proximity, temperature etc) from “things”, like cars, machines, and devices, over the internet. Data collected can then be translated into actionable insights. The more data-driven the world becomes, the more valuable IoT can be for all kinds of businesses.

The Internet of Things isn’t just an interesting concept, showcasing the potential of a digitized world, it can be a significant solution for any company investing in a future of greater efficiency and improved productivity. IoT can pave the way for enhanced connectivity in the business landscape, making it easier to transfer data from one environment to another.

The Internet of Things is also an important enabler behind the rising trend of “automation” in the business landscape, making it increasingly crucial for evolving brands. While manufacturing companies seem to be the brands making the largest investment in IoT right now, there are opportunities in a host of different industries. Some of the biggest benefits of IoT include:

  • Improved productivity: IoT, combined with artificial intelligence can help to automate routine tasks, so human resources can be used more effectively. This allows for better productivity, and higher levels of employee satisfaction in the workplace.

The Growing Pains of the IoT Industry

So, if IoT is so impressive, why hasn’t every company and business leader embraced this technology in full? While adoption of IoT is certainly increasing, there have been some growing pains preventing this technology from reaching its full potential in recent years.

To some extent, the issues preventing adoption of IoT are the same as those preventing the rapid acceleration of various other forms of digital tools, such as uncertainty, lack of expertise in the area, and lack of funding. Processing massive amounts of IoT data also requires an exponential increase in the amount of processing power companies can access.

Ultimately, there are a number of growing pains holding us back from a new era of full IoT adoption. In fact, one study found around 60% of people believe IoT deployments look good in theory, but can often be more complicated to implement than expected.

One common issue companies face with IoT adoption is a lack of interoperability between devices. Just because a device is enabled for IoT doesn’t necessarily mean it speaks the same programming language as another product. While there has been a rapid increase in the number of IoT solutions and platforms over the years, each solution has its own IoT APIs, infrastructure, and devices, leading to a consistent issue with interoperability.

Another major issue concerning many brands is security. The IoT environment isn’t always as secure as it could be, and developers have often rushed connected solutions to market without the right safeguards in place. We’ve seen examples of countless companies struggling with this problem over the years. For instance, the Mirai botnet event allowed hackers to assemble an army of connected devices and use them to launch a massive DDoS attack against the US.

While SD-WAN can’t solve all of the problems IoT technology has to overcome, it can address one very specific issue: access to the right network resources. IoT devices require adequate network resources once they’re up and running. If these devices are left unchecked and improperly managed, they can often lead to a variety of performance issues. This is where SD-WAN comes in.

The Introduction of SD-WAN for IoT Deployments

Most companies know SD-WAN today as the powerful tool designed to improve their communication strategies and app access in a distributed environment. However, SD-WAN has a huge range of use cases, including an opportunity to significantly improve the SD-WAN marketplace.

Software-Defined Wide Area Networking is a networking methodology which decouples networking hardware from the mechanism it uses for control. This can be particularly useful for IoT deployments. With SD-WAN, companies can gain the real-time stability and visibility required to control comprehensive IoT devices in an evolving global network.

The sheer level of control provided by SD-WAN means it’s possible for companies to centralize access to their range of powerful connected tools. Network administrators can more conveniently manage all of their connected endpoints from a single location. Additionally, SD-WAN can simplify the headaches of traffic management, minimizing the risk of network outages, and improving security at the same time.

For companies looking into the benefits of IoT for efficiency, cost-savings and countless other use cases, SD-WAN can be a lucrative and intelligence solution for streamlining communications. You can improve the flow of data from IoT edge devices from your centralized data center, and access crucial information more rapidly, allowing for true real-time insights.

With SD-WAN, companies can prioritize the flow of data from specific applications, and choose the best WAN path for the traffic, reducing issues with latency, while simultaneously securing sensitive data running through network links. As SD-WAN evolves and new opportunities like SASE emerge, we’ll see even greater opportunities for securing IoT on the network edge.

The Benefits of SD-WAN for IoT Deployments

For IoT deployments and applications, SD-WAN offers a level of end-to-end visibility and control it’s difficult to access anywhere else. Increasingly, experts are beginning to see SD-WAN as the ultimate partner for IoT deployments, just as its becoming an important tool for the introduction of other digitally disruptive tools like UCaaS.
