One of the most significant drivers of change in networking, IT, and OT alike, has been the adoption of cloud technology. The shift toward cloud-based processing and design is not just a trend—it represents a paradigm shift in how OT networks are built, and how building automation is managed, monitored, and maintained.
Let’s examine how cloud computing is shaking up OT networks, compare the perks of remote access to on-premise setups, and consider what these changes mean for businesses that rely on OT systems.
What Exactly is “The Cloud”, Anyway?

“The cloud” refers to the delivery of computing resources over the Internet rather than through on-premise resources. Among many other pluses, it means a big boost in agility, flexibility, and scalability at much lower costs without the on-premise investments to process, host, and support the data and software needed to service your facilities.
This is a pretty stark contrast to traditional OT networks that were designed to operate in isolated environments, with hardware and software hosted on-premise. While this approach provided security and control, it also introduced significant limitations. On-premise systems often require substantial upfront investment, ongoing maintenance, and regular updates to remain secure and functional.
The cloud offers a new way forward, addressing these challenges while opening the door to new possibilities. As Ranjan Banerji and Kristine Martz write in their AWS article How to securely extend utility OT data to the cloud, “OT systems are rich with data that could be used to support simulations, incident response, and business decisions, but the networks they are connected to are often limited by the storage and compute power available onsite.”
Powering IT/OT Convergence
The cloud is also driving IT and OT network convergence by providing a unified platform where data from both systems can be processed, analyzed, and managed seamlessly. The cloud enables real-time data sharing and integration across both domains, fostering collaboration and improving overall efficiency. Organizations can break down barriers between IT and OT, enabling smarter decision-making, predictive maintenance, and streamlined operations.
How Is The Cloud Reshaping OT Networks?
Here’s just a few examples of how some organizations leverage cloud networks to augment their OT networks:
Scalable Processing Power
One of the biggest challenges for OT networks is processing the vast amounts of data generated by connected devices. In particular, IoT subnets, smart sensors, controllers, and other devices within a building or facility can potentially generate terabytes of data daily. On-premise BAS servers can struggle to keep up with this demand, leading to slower analysis and decision-making.
Cloud platforms, on the other hand, offer virtually unlimited processing power. Organizations can scale their computing resources up or down based on real-time needs. This scalability ensures that even the most data-intensive applications, such as predictive maintenance and real-time monitoring, can run efficiently.
Several companies also offer virtual private clouds for sensitive OT networks, like utilities, concerned with data privacy and security.

Fun Fact: In 2024, Optigo Networks leveraged the cloud to help 1300+ companies process thousands of packet captures of BACnet data—nearly 15 terabytes— from their OT networks!
Centralized Management and Visibility
With the cloud, organizations can both centralize and remotely manage their OT networks. Instead of siloed systems scattered across multiple locations, data from various facilities can be collected and processed in a single platform. This centralized approach enhances visibility, making it easier to monitor system health, detect anomalies, and identify potential security threats.
For example, a company with facilities across multiple cities can use a cloud-based platform to oversee all operations from a single dashboard. This level of oversight is nearly impossible to achieve with on-premise systems alone.
Improved Collaboration
The cloud facilitates seamless collaboration between internal teams and external partners. Vendors, systems integrators, and other stakeholders can securely access OT network data from anywhere, enabling faster troubleshooting and more effective joint efforts. This level of collaboration is especially valuable during emergencies when rapid response times can prevent downtime or mitigate damage.
We also introduced seamless collaboration in the cloud. With OptigoVN’s new Site Scope+ add-on, you can share OT network diagnostics with anyone inside or outside your organization. See all the details here.
Enhanced Security
While security is often cited as a concern when moving to the cloud, modern cloud platforms are designed with robust security measures. Encryption, multi-factor authentication, and continuous monitoring are standard features.
Cloud providers also frequently update their systems to address emerging threats, reducing the burden on individual organizations and smaller teams to maintain their security infrastructure.
There is a caveat to this, though. Security remains a top concern, as unauthorized access to OT networks can still present significant risks. Organizations must implement robust security measures, such as VPNs, encryption, and strict access controls, to mitigate this.
Cost Savings
On-premise solutions often require significant investments in hardware, software, and personnel to maintain the infrastructure. Remote access, powered by cloud technology, reduces these costs by shifting much of the workload to scalable cloud platforms. Additionally, it minimizes travel expenses associated with on-site troubleshooting.
Remote Access vs. On-Premise Solutions
Remote access is a game-changer for technicians and system integrators tasked with maintaining OT networks. For technicians, the ability to remotely monitor and manage devices reduces the need for frequent site visits, enabling them to address more issues in less time.
System integrators also benefit from this remote capability, as they can oversee multiple client networks from a centralized location. This means quicker problem resolution, more efficient workflows, and better service for end users.
This flexibility is invaluable in today’s interconnected world, where many teams are geographically dispersed. It also allows experts to address issues promptly, reducing the need for costly site visits.
In addition, remote access simplifies training and onboarding. Technicians and integrators can familiarize themselves with a network’s setup without needing to be on-site, saving valuable time and resources. This is particularly useful for large-scale projects or facilities spread across multiple locations.
On-premise solutions still hold value in certain scenarios. For example, facilities in remote locations with limited internet connectivity may rely on local infrastructure to maintain operations. Similarly, organizations with highly sensitive data may prefer the control and isolation offered by on-premise systems. However, the trade-offs—including higher costs, limited scalability, and reduced flexibility—make on-premise solutions less appealing for many businesses.
Embracing the Cloud: Key Considerations
For organizations looking to transition to cloud-based OT networks, careful planning is essential. Here are some key considerations:
1. Evaluate Your Needs. Before moving to the cloud, assess your organization’s specific requirements. Identify which OT network systems and processes would benefit most from cloud adoption and which might need to remain on-premise.
2. Choose the Right Partner. Not all cloud platforms are created equal. Look for providers with a proven track record in OT network management, robust security measures, and scalable solutions.
3. Prioritize Security. Work with your cloud provider to implement comprehensive security measures, including encryption, multi-factor authentication, and continuous monitoring. Regularly review and update your security protocols to address evolving threats.
4. Train Your Team. Ensure that your team is equipped to manage cloud-based systems effectively. Provide training on new tools and processes, and foster a culture of continuous learning to keep up with technological advancements.
