If your inbox looks anything like mine this week, it's been packed with updates and analysis from Hannover Messe 2025. My colleagues at ARC Advisory Group have been actively publishing ARCwires, breaking down the many announcements and highlighting the latest industrial innovations. I’ve been keeping a close eye—through pre-event briefings, insights from our team on-site in Germany, and ongoing conversations with clients.
Having spent decades immersed in industrial automation, factory operations, supply chain, and enterprise software—my gray hairs tell the story—one announcement at Hannover Messe 2025 stood out in particular: the partnership between Rockwell Automation and Amazon Web Services (AWS).
For those who know me, you might remember my time at Microsoft (and yes, my LinkedIn profile is still live: https://www.linkedin.com/in/colinmasson/). That experience gave me a lasting appreciation for Microsoft’s foundational role in the industrial world. For decades, it was almost a given that factories “ran on Microsoft”—not just as a saying, but in practice. Windows Embedded was widely adopted across industrial automation vendors, and Microsoft Office tools like Excel and Access quietly filled countless automation and process gaps on the plant floor.
The industrial sector—which includes manufacturing, energy, logistics, and beyond—is in the midst of a major transformation. In pursuit of greater efficiency, resilience, and intelligence, organizations are accelerating the modernization of their operational technology (OT) environments. Technologies like cloud computing, Edge AI, and the Industrial Internet of Things (Industrial IoT) are driving this change. Among the many players in this space, the competition for industrial cloud platform leadership is intensifying—especially between Amazon Web Services (AWS) and Microsoft Azure.
Microsoft's Deep Enterprise and Industrial Roots
Microsoft has long held a strong foothold across both enterprise and industrial domains. It's important to recognize the breadth of its strengths across multiple layers of the ecosystem:
Operational Edge Presence: Well before the cloud race gained momentum, Microsoft had already established a strong presence on the factory floor through Windows Embedded (now Windows IoT), which has powered countless HMIs, controllers, and industrial devices for decades.
Enterprise Software Dominance: Microsoft’s unmatched leadership in office productivity through Microsoft 365 has made it the backbone of communication and documentation across most industrial organizations. In addition, Dynamics 365 provides a strong foundation in both CRM and ERP, seamlessly connecting business processes from sales to shop floor operations.
Early Industrial Cloud & Data: Building on its existing relationships, Microsoft Azure gained an early advantage in industrial IoT and data analytics platforms. With many on-premises systems—especially Manufacturing Execution Systems (MES), which some jokingly dubbed “Microsoft Excel Spreadsheet” due to widespread manual data handling—there was a natural pathway for integration with Azure.
Robust Partner Ecosystem: Microsoft’s long-standing presence in the industry has cultivated a vast partner ecosystem, rich with expertise in the Microsoft stack—further reinforcing its stronghold in the industrial landscape.
Framing the Battle for Industrial Cloud and OT Platform Leadership
It’s important to note that AWS does not currently have direct counterparts to Microsoft 365, or the breadth of CRM/ERP offerings found in Dynamics 365. So, when we talk about AWS “closing the gap,” it refers specifically to the fast-moving space of industrial cloud services, edge platforms, Industrial IoT enablement, data analytics, and AI/ML capabilities tailored for Operational Technology (OT). This core infrastructure and platform layer for modern industrial systems is where the competition with Azure is growing most intense.
Hannover Messe 2025: A Tale of Two Strategies?
Hannover Messe, the world’s premier trade fair for industrial technology, often reflects the shifting priorities and strategies of major tech vendors—and 2025 was no exception. This year’s event revealed notable differences in how AWS and Microsoft are approaching the industrial cloud platform space:
AWS: AWS made a significantly larger and more visible impression than in previous years. Its messaging focused heavily on OT integration and industrial data solutions. Key highlights included major updates to AWS IoT SiteWise for improved edge processing and digital twin support, the introduction of generative AI tools tailored to predictive maintenance and quality control, and high-profile customer wins in the automotive and CPG sectors. It also announced strategic partnerships with industrial hardware leaders such as Siemens and Rockwell Automation, signaling a deepening focus on factory-floor integration. The overall message was clear: AWS is investing aggressively in industrial innovation.
Microsoft Azure: Azure also maintained a strong presence, but its approach to the industrial platform space appeared more partner-centric. While showcasing updates to Azure IoT Operations and Dynamics 365 modules like Field Service and Supply Chain, much of its messaging and booth space highlighted solutions developed by its partner ecosystem. Its announcements focused on embedding AI features like Copilot into existing Azure services rather than introducing entirely new industrial platforms at the scale AWS did. The strategy seemed to be aimed at empowering partners to deliver vertical-specific solutions using the Azure foundation.
Evidence of Shifting Tides?
Beyond the buzz of Hannover Messe, anecdotal insights and market indicators suggest a shifting momentum in the industrial cloud platform race:
AWS’s Investment Surge: Evidence points to AWS significantly increasing its focus on industrial solutions. Over the past 18 months, LinkedIn job postings reveal a notable rise in roles such as “Industrial IoT Solutions Architect,” “Manufacturing Cloud Specialist,” and “Digital Twin Engineer.” In parallel, AWS has ramped up its sponsorship and presence at major global manufacturing and industrial tech events throughout 2024 and into 2025—reflecting a clear push for stronger market visibility and engagement in this space.
Microsoft’s Partner-Centric Evolution: While Microsoft remains a major force, feedback from partners and industry analysts indicates a potential strategic shift in how it approaches industrial platform development. The perception is that Microsoft may now be leaning more on its extensive partner ecosystem to deliver industry-specific solutions, possibly slowing its own direct investment in new first-party OT and Industrial IoT platform services. Recent changes to its partner programs—focusing on co-selling and empowering partner-led implementations—seem to support this approach. This doesn’t necessarily signal reduced commitment, but rather a move toward enabling partners to lead in specialized industrial applications.
A Leveling Playing Field: Cloud, Edge, and AI
This potential shift is unfolding at a pivotal moment. Modernizing industrial architectures is no longer just about moving workloads to the cloud—it’s about striking the right balance between centralized cloud services and distributed edge computing. Processing data closer to the source—whether on the factory floor or at remote energy sites—is essential for real-time analytics, low-latency control, and operational resilience.
At the same time, the integration of Artificial Intelligence (AI) is emerging as a key differentiator. From predictive maintenance and quality inspection to supply chain optimization and process automation, AI is reshaping industrial operations. Vendors that can deliver seamless AI integration across both cloud and edge environments, tailored to real-world industrial needs, are gaining a clear advantage.
This evolving interplay between cloud, edge, and AI is leveling the playing field in the industrial platform space. AWS, with its robust Infrastructure-as-a-Service (IaaS) capabilities, expanding edge offerings like Outposts and IoT Greengrass, and deep investments in AI/ML, is increasingly well-positioned to challenge Microsoft’s established role. Its approach, centered on offering modular building blocks, enables industrial clients and partners to develop highly customized solutions.
The Race Intensifies on the Industrial Platform Front
While Microsoft Azure continues to benefit from its broad enterprise integration, longstanding presence in OT through Windows IoT, and strength in adjacent domains like productivity tools and business applications, the core industrial cloud and edge platform landscape is clearly evolving. AWS is emerging as a formidable contender in this space, with focused, well-funded efforts to address industrial use cases—reflected in both its recent initiatives and prominent presence at Hannover Messe.
There’s a growing perception that Microsoft is increasingly relying on its partner ecosystem to deliver specialized OT and Industrial IoT solutions, while AWS is investing directly in core platform capabilities. This signals a shift in competitive dynamics. As industrial organizations work through the complexities of cloud-edge architectures and look to embed AI more deeply into their operations, the decision between cloud providers is becoming less about legacy footprints and more about who offers the most forward-looking, flexible, and industry-specific platforms.
The industrial cloud race is clearly gaining momentum—and it’s only just beginning.
