ISA's New Position Paper on Cloud Computing in Operational Technology
The International Society of Automation (ISA), a prominent organization within the automation sector, has recently published a pivotal position paper entitled
"Cloud Computing in OT Environments." This document delineates the organization's stance regarding the integration of cloud technologies within operational technology (OT) frameworks. As the lines blur between OT and information technology (IT), this new guidance aims to help leaders in the industry understand when and how to embrace cloud solutions responsibly.
Significance of the Paper
The focus of this paper is on the critical intersection of cloud computing and OT, emphasizing the advantages that cloud technologies can introduce while also addressing the inherent risks associated with such transitions. Within OT systems—characterized by their real-time, closed-loop controls—there are specific needs regarding reliability, availability, and latency, which necessitate a careful approach to cloud integration.
As Claire Fallon, the Executive Director and CEO of ISA, puts it:
"Cloud is not a one-size-fits-all solution for OT, but when applied to the right use cases, it can unlock meaningful improvements in resilience, insight, and efficiency." This statement captures the essence of the paper’s message: while cloud technology can add substantial value in OT contexts, its adoption must be strategic and well-considered.
Key Areas for Cloud Application
The position paper outlines several distinct domains where cloud computing can make a significant impact in OT:
- - Remote Operations: Cloud infrastructure enables remote facilities to benefit from secure, redundant operations, bolstered by disaster recovery capabilities.
- - Predictive Maintenance: Utilizing advanced analytics, machinery providers can analyze data (such as vibration metrics) to foresee failures, thereby minimizing downtime and associated costs.
- - Smart Manufacturing: Companies can enhance their supply chain management—from procurement to logistics—using cloud solutions for data integration and analysis.
- - Energy Management: Cloud computing facilitates the handling of substantial datasets related to smart grids and energy systems, contributing to more efficient energy dispatch and management.
Challenges of Implementing Cloud in OT
The paper doesn't shy away from discussing the challenges that come with migrating to cloud environments, which differ substantially from traditional IT settings. Notable issues include:
- - Cybersecurity: The broader attack surface necessitates a robust defense strategy to safeguard OT environments.
- - Latency: Time-sensitive operations may be ill-suited for cloud execution, which can introduce delays.
- - Reliability: There is a need to ensure that systems can function reliably even when cloud connectivity is interrupted.
- - Compatibility: Integrating legacy systems with modern cloud platforms poses significant hurdles.
- - Culture and Change Management: Organizing teams familiar with on-premises workflows to adapt to new cloud-centric processes will be a necessary effort.
ISA's Commitment to Cloud Integration
ISA has established itself as a leading developer of automation standards, providing the frameworks and competency programs required for responsible cloud implementation. For instance, the ISA/IEC 62443 series offers a flexible and comprehensive approach to ensuring cybersecurity within industrial automation and control systems, which is essential for any cloud strategy implemented in OT environments.
In addition, the ISASecure® certification program allows for the validation of products and practices conforming to strict cybersecurity measures.
This position paper is not just a guidance document; it aims to galvanize various stakeholders—industry leaders, policymakers, and academic institutions—to work together on developing standards and educational initiatives that will promote resilient cloud infrastructures capable of benefiting the overall industrial ecosystem.
The position paper titled
"Cloud Computing in OT Environments" is currently available for access at

Conclusion
The advent of cloud computing in operational technology holds great promise but must be approached with thorough consideration of its unique challenges. ISA's latest position paper aims to inform and guide stakeholders as they navigate this rapidly changing landscape, emphasizing the importance of maintaining safety, security, and reliability as cloud solutions are integrated within OT environments.
