IDC: Why the right networking approach is foundational to agentic AI

IDC research finds that networking infrastructure is a critical bottleneck for enterprises moving agentic AI from pilot to production, with security concerns (32.6%), automation challenges (26.8%), and staff limitations (24.7%) cited as top barriers. The report, sponsored by Google Cloud, argues that infrastructure-level networking controls are essential to manage the distributed, dynamic interactions of agentic AI systems.

Editor’s note: Today we hear from IDC on the results of its 2026 AI in Networking Special Report Survey exploring the enterprises' concerns about networking infrastructure to support the rise of agentic AI in their organizations. The survey was sponsored by Google Cloud. Enterprises are moving quickly on AI pilots, but the move from pilot to production remains uneven. While AI models remain important, IDC research indicates that the pilot-to-production bottleneck is primarily infrastructure-centric, with core networking concerns emerging as one of the leading drivers of AI project delays and abandonment. In IDC's 2026 AI in Networking Special Report Survey: 32.6% of respondents cite security concerns: As AI workflows become more distributed and autonomous, enforcing consistent security and governance becomes more difficult. 26.8% of respondents cite challenges in automation: Manual operations and fragmented controls can slow deployment and make AI environments harder to scale. 24.7% of respondents cite staff time and talent restrictions: Limited skills and operational bandwidth can constrain an organization's ability to move AI initiatives into production. Agentic AI specifically heightens these concerns by introducing more distributed and dynamic interactions across applications, services, APIs, tools, and data sources. In production environments, these interactions often span different agent frameworks, model providers, clouds, open-source tools, SaaS APIs, and internal applications, expanding both the operational scope and the security and governance surface area. Networking is the primary enabler of agentic interactions and plays a foundational role for intracloud and intercloud network- and services-layer connectivity, end-to-end security, and consistent governance. In agentic systems, networking increasingly extends into tighter service-centric controls that govern how distributed services identify one another, communicate, and exchange data securely. While AI workloads in general are increasing east-west traffic demands, agentic AI adds an additional layer of complexity by creating dynamic interactions that require tighter policy, visibility, and control closer to the application workflow. From an infrastructure perspective, networking is much more than just a connectivity function. It is part of the infrastructure platform control plane that applies policy-based controls, supports observability, and helps maintain consistent security and governance across an AI agent's activity. This is significant because framework-level controls alone become insufficient in environments where agents and services span different runtimes, clouds, deployment models, and operating domains. That is why an infrastructure-level approach becomes key. It does not replace application frameworks or orchestration environments, but it provides broader and more consistent policy implementation across a complex architectural landscape. As agentic AI becomes more autonomous and distributed, organizations need these controls built in as part of the infrastructure to reduce fragmented observability, inconsistent policy application, and unmanaged shadow agent activities. From a cloud infrastructure standpoint, this is where cloud network services become strategically important. Agentic AI systems are inherently fragmented because of underlying distributed workflows. Enterprises are already navigating a rapidly evolving landscape of business requirements, open-source components, emerging protocol standards, and new architecture patterns. In this context, choices between best-of-breed point solutions and platform-based approaches should be strategic rather than ideological. Best-of-breed capabilities may be necessary to address specific technical requirements. But it is also true that point solutions introduced across a distributed agentic AI landscape can create inconsistent policies, operational complexity, and governance gaps. IDC research reflects this tension. In IDC’s 2026 AI in Networking Special Report Survey, organizations remained divided between platform and best-of-breed preferences for AI workloads; among respondents who favored platforms, the main reasons cited were stronger security 32.9% , reduced complexity 27.7% , and faster deployment 24.2% . In IDC's view, a balance is important. Platforms can provide a consistent operational and policy foundation for AI deployments, but at the same time, they need to be modular and extensible to allow the inclusion of best-of-breed functionality as part of the platform toolset. The right platform for agentic AI should be open, flexible, and able to evolve. It should support integration with third-party and open-source tools, allow insertions of needed security and observability functions, and adapt without complete architectural rework. This is a period of technology disruption. Businesses must meet their AI objectives while carefully managing dynamic agentic AI systems. In this environment, networking not only remains a connectivity piece of the AI infrastructure but becomes foundational to how organizations establish operational control, apply policy consistently, and maintain end-to-end trust across agentic workflows. As agentic AI systems continue to evolve, the demands they place are unlikely to be addressed through best-of-breed point solutions alone. Operationalizing agentic AI at scale will require organizations to leverage the right networking approach, supported by infrastructure platforms that are open, flexible, and extensible, enabling a cohesive and adaptable security and governance framework. Message from the sponsor The autonomous and non-deterministic communications of agentic applications pose challenges for which the infrastructure and governance models of the cloud-native era are not prepared. In the agent-native era, an infrastructure-led approach is required to enable agentic applications at scale in production with effective governance and observability. An extensible platform based on open standards is critical in enabling the agentic journey today and through its maturity.
