Cumulus Networks

Cumulus Networks: The Leaders in Web-Scale Networking

Cumulus Networks is leading the transformation of bringing web-scale networking to organisations of all sizes. Cumulus’ 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 centres.

Cumulus customers can run their data centre networks the way Google and Facebook have done for years — highly automated, flexible and efficient, without all the development time or expensive, specialised hardware.

Instead of focusing on siloed solutions, Cumulus transforms every stage of the networking lifecycle – from architecture, design, build, deployment and operations – with 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. Customers access flexibility, efficiency, speed and choice with a unified stack and a feature set designed for the digital age.

With Cumulus NetQ, organisations are empowered with full network validation and reduced downtime, and Cumulus Host Pack extends network visibility into containers.

The network is a critical part of the data centre that has traditionally been a bottleneck for rapid deployment of applications. From provisioning and deployment to monitoring and operations, Cumulus believe in completely transforming the industry by enabling a web-scale IT architectural approach.


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 centres.

Why choose Cumulus Linux?

Cumulus Linux is the only solution that allows you to affordably build and efficiently operate your network like the world’s largest data centre operators, unlocking vertical network stacks.

Built For Automation First – Enjoy networking that’s consistent and repeatable

Complete Standardisation – With Linux across the entire data centre, you’ll reduce complexities and get complete interoperability


Upgrade your network operations from a manual, reactive, box-by-box approach to one that is automated, informed and agile

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.

Why choose NetQ?

With its focus to help operationalise Cumulus Linux, Cumulus NetQ is designed to run on any Linux operating system or application across the data center — like Ubuntu, CentOS and RedHat — expanding visibility from the Linux-based switch to the Linux-based hosts and containers. The metadata it collects across these elements ensures visibility and intelligence in the health of the network, making sure everything is behaving as intended.

NetQ is unique in this capability since it is the only telemetry agent in the market that is integrated with container orchestrators and the Netlink interface to the Linux Kernel, which provides real-time access to Linux networking events across the routed fabric. Using Cumulus NetQ advances network operations to drive CI/CD, web-scale initiatives through an automated and intelligent approach.

Improve Network Uptime – Deep packet tracing validates that you have the true end-to-end connectivity you expected.

Reduce Management Complexity – Receive event notifications via Slack or Pager Duty so that any part of the IT team can be alerted and start troubleshooting.

Increase Network Agility – All networking events are time-stamped, so you can ID all historical changes to pinpoint issues.

Get Unparreled, Fabric-Wide Visibility – Remove blind-spots by running a single Show, Trace or Check command to troubleshoot the entire network, from any location.
