“Our comprehensive product portfolio provides you with all the tools you need to affordably build and efficiently operate your network like the world’s largest data centers.”
Cumulus Networks is leading the transformation of bringing web-scale networking to organizations of all sizes. Instead of focusing on siloed solutions, at Cumulus Networks, we transform every stage of the networking lifecycle — from architecture, design, build, deployment and operations — with our three products, Cumulus Linux, Cumulus NetQ and Cumulus Host Pack.
Cumulus Linux is the most flexible network operating system available because it runs on Linux. Our customers access flexibility, efficiency, speed and choice with a unified stack and a feature set designed for the digital age. With Cumulus NetQ, we empower organizations with full network validation and reduced downtime, and Cumulus Host Pack extends network visibility into containers. Cumulus Networks is transforming the networking industry by bringing web-scale IT and innovations to the data center.
The network is a critical part of the data center that has traditionally been a bottleneck for rapid deployment of applications. From provisioning and deployment to monitoring and operations, we believe in completely transforming the industry by enabling a web-scale IT architectural approach.
Boldly Breaking the Status Quo
Our founding team is comprised of some of the industry’s most renowned technology innovators responsible for the some of the most significant advancements in networking. We broke into the industry with the first Linux operating system for networking hardware — filling a critical gap in realizing the true promise of the software-defined data center.
We are not just defining the future of networking. We are actively creating it with our customers and partners. Our list of product features and services are heavily dominated by our own in-house innovations and developments, and our leadership team and engineering talent are bringing thought leadership and support to the open networking community.
The Leaders in Web-Scale Networking
Cumulus Linux: The world’s most flexible open network operating system for bare metal switches. Cumulus Linux is a powerful open network operating system that allows you to automate, customize and scale using web-scale principles like the world’s largest data centers.
Cumulus NetQ: With the onset of web-scale initiatives, microservices, containers, big data, virtual machines and more, changes to the network happen constantly. If there’s ever a connection problem, the impact is significant. Yet trying to identify what went wrong in this virtual, ephemeral network is like trying to find the proverbial needle in a haystack.
Cumulus NetQ reduces network operational complexity by providing actionable insight into every trace and hop in the Linux-based data center — from the container, virtual machine or host, all the way to the switch and port. With NetQ, you can validate network designs and simplify troubleshooting with real-time insight to Linux networking events across the modern data center.
Voyager: Transforming the data center interconnect of today. Voyager is the industry’s first open packet optical platform — unifying IP and optical to massively reduce complexity and costs.
In the past, the hardware and software solutions for the data center interconnect space have been inflexible and costly. With the boom of digital innovation, these organizations need more bandwidth and flexibility in their data center interconnect solutions — and they need it to be cost-efficient. Voyager is the answer.
Testimonies from the Clients
“Cumulus Networks support team was excellent – they were knowledgeable and responsive.”
- Sid Stuart, Director of Operations at OpenWager
“With Cumulus Linux, manual configuration is no longer needed for provisioning new racks, applying the new policy or responding to security advisories. The lifecycle is now entirely automated.”
- Alan Meadows, Chief Architect at NephoScale
“With Cumulus Linux, we were able to move away from a Fibre Channel/SAN framework to a more modern way of supporting our business growth.”

Prior to Instart, Josh spent six years at VMware and held leadership roles in both sales and business development as the company scaled from less than $100M to more than $1B in sales. Before VMware, Josh was a field rep for CommVault Systems. He began his career as an analyst and associate in investment banking where he advised technology companies on financing and M&A strategies.
A Bay Area native, Josh received a BA from the University of California, Berkeley and an MBA from Columbia Business School.
JR Rivers, Co-Founder, and CTO: JR is a co-founder and CTO of the company where he works on the company, technology, and product direction. JR has been involved with networking since Ethernet only ran on coaxial cables. He’s worked on some of the most foundational networking products of their time, from early Network Interface Cards
at 3Com through switching and routing products at Cisco. JR’s early involvement in home-grown networking at Google and as the VP of System Architecture for Cisco’s Unified Computing System both helped fine-tune his perspective on networking for the modern datacenter.
“Our customers can run their data center networks the way Google and Facebook have done for years — highly automated, flexible and efficient, without all the development time or expensive, specialized hardware.”
