As the digital economy accelerates, the demand for agile, scalable, and intelligent infrastructure is growing exponentially. In response, the Linux Foundation—a global leader in building open technology ecosystems—launched the Open Programmable Infrastructure (OPI) project. This initiative brings together industry leaders to define open standards for Data Processing Units (DPUs) and Infrastructure Processing Units (IPUs), setting the foundation for a new era of programmable, composable infrastructure.
The Motivation Behind OPI
Modern workloads, such as AI/ML, 5G, and edge computing, are placing unprecedented pressure on traditional server architectures. General-purpose CPUs, which were once sufficient for most computing tasks, now struggle to meet the specialized performance and efficiency demands of emerging applications.
DPUs and IPUs offer a compelling solution. These hardware accelerators are specifically designed to offload infrastructure functions, such as networking, storage, and security, thereby enabling improved resource utilization and enhanced system performance. However, fragmentation in software and hardware ecosystems has limited broader adoption. The OPI project addresses this challenge by promoting open standards, APIs, and frameworks, ensuring interoperability across vendors and platforms.
FusionLayer’s Motivation for Joining the OPI Project
One of the recent contributors to the OPI project is FusionLayer, a virtual networking pioneer known for its innovations in network automation, multi-cloud orchestration, and service abstraction. As programmable infrastructure takes center stage, FusionLayer’s involvement signals a strategic alignment with the OPI project’s mission to simplify and standardize infrastructure programmability.
With its strong background in managing complex IP address spaces and automating network provisioning, FusionLayer contributes essential capabilities that enhance OPI’s ability to support real-world, large-scale deployments.
Shared Vision: Programmable, Cloud-Native Infrastructure
The OPI project’s vision is to bring cloud-native principles down to the infrastructure layer, making networking, storage, and compute as composable and programmable as the applications that run on them. This vision aligns closely with FusionLayer’s mission of abstracting and automating foundational network services.
FusionLayer’s commitment is evident in its leadership in Secure Zero Touch Provisioning (SZTP)—an IETF-defined standard designed to automate the secure onboarding of infrastructure devices. Recognizing the critical role SZTP can play in programmable environments, FusionLayer developed and open-sourced an SZTP client, enabling seamless and secure bootstrapping of SmartNICs, IPUs, and other programmable components. This contribution enhances the OPI ecosystem by allowing rapid, policy-driven provisioning at scale.
Business Benefits: Agility, Efficiency, and Control
For enterprises and cloud providers, the collaboration between OPI and FusionLayer delivers tangible business value:
• Performance & Efficiency: Infrastructure offload reduces CPU contention and optimizes system throughput.
• Cost Reduction: Automation and specialized hardware lead to improved utilization and lower total cost of ownership (TCO).
• Faster Time-to-Service: Automated provisioning with open standards accelerates service rollout and iteration.
• Vendor Independence: A standardized framework mitigates lock-in and opens the door to broader innovation.
FusionLayer’s software-defined IPAM and orchestration solutions further amplify these benefits by enabling centralized control and dynamic provisioning across cloud, edge, and hybrid environments.
End-User Value: Enhanced Digital Experiences
Although end users may never interact with a DPU or SmartNIC directly, the results of this technology shift are unmistakable. Faster application responsiveness, reduced latency, enhanced security, and more resilient services are just a few of the improvements made possible by the programmable infrastructure underpinning modern digital services.
With OPI setting the standards and FusionLayer enabling the automation, businesses are better equipped to deliver exceptional user experiences consistently and at scale.
Looking Ahead
As data volumes surge and applications become more distributed, infrastructure must evolve from static and siloed to programmable and intelligent. The Open Programmable Infrastructure (OPI) project, under the guidance of the Linux Foundation, is laying the technical and governance foundation for this future.
Through its contributions, particularly in the areas of SZTP and network service abstraction, FusionLayer is helping to ensure that infrastructure automation keeps pace with innovation. Together, OPI and its contributors are building the fabric for tomorrow’s high-performance, cloud-native world.
