Kube-OVN Survey Report: Container Network Usage and Kube-OVN Adoption Trends (Second Edition)

In early August, the Kube‑OVN community, together with SDNLab, launched the second edition of the "Container Network Status and Kube‑OVN Usage" survey, which attracted many Kubernetes and networking professionals and gathered extensive feedback during the Kube‑OVN Meetup.

The annual survey aims to capture a comprehensive view of enterprise container network adoption and Kube‑OVN usage to inform community roadmap planning.

Over a month, 267 valid questionnaires were received from practitioners in Internet, finance, industry, manufacturing, education and other sectors. The report analyses this first‑hand data and compares it with the 2020 first‑edition results.

Respondent profile shows 32% developers, 31% operations, 19% architects. Internet companies account for 57.3% (down from 60%), while traditional sectors such as government, finance, industry, telecom, manufacturing and education rise to 35.4% (up from 30.5%).

Regarding container runtime environments, 68.8% of surveyed enterprises run containers on virtual machines (private cloud), surpassing the 60.5% in the first survey, and public‑cloud usage climbs to 50%.

Kube‑OVN’s market share in container networking jumps to 40%, far exceeding the 28.9% recorded in the first edition.

Workload analysis shows a growing demand for IPv6 or dual‑stack networking, while multi‑tenant VPC solutions and integration with physical networks remain essential for most users.

Users’ expectations focus on three technical directions: tighter integration with KubeVirt, enhanced VPC capabilities, and the introduction of eBPF‑based features.

Feature usage data indicate that subnet, static IP, and underlay/VLAN functions are leading, while VPC, cluster interconnect, and traffic mirroring see balanced adoption, reflecting deeper and more differentiated usage of Kube‑OVN.
