Summary

A network operating system, or network operating system, is an essential component of a disaggregated technology stack running on bare-metal servers and switches using merchant silicon. Combining the agility of software feature development with the performance and economics of bare metal, network operating systems enable extremely scalable and cost-effective networks.

The first GigaOm Radar Report for the evaluation of network operating systems, open source projects and vendors was released in early 2021. After evaluating 19 different commercial and open source network operating systems, six vendors were included in the ring of the leader, eight in that of the challenger. ring, and five in the newcomer’s ring. However, with the COVID-19 pandemic driving the shift to remote working, 2021 has been a pivotal year for many network operating system vendors, as evidenced by new acquisitions, new capabilities, new investors, new partnerships and new customer commitments.

While some vendors have focused on alternative go-to-market initiatives and revising roadmaps influenced by new acquisitions, others have learned lessons from the COVID-19 pandemic. These vendors set out to create new value, develop new partnerships, expand feature sets, implement automation, support new platforms, scale their installed base, and position themselves for future growth, all with varying results.

As a maturing technology, network operating systems are being adopted by organizations to enable new use cases. This GigaOm Key Criteria report describes the critical criteria and evaluation factors for selecting a network operating system. The corresponding GigaOm Radar reports provide an overview of the major network operating system vendors and their offerings available today. Together, these reports can help educate decision makers, providing essential information for network automation initiatives.
