Kubernetes-Native Network Device Projects

Research question: Are there Kubernetes-native projects analogous to Ze (a Linux-host-level Network OS with native BGP) that "turn a cluster into a network device" using operators and CRDs?

Short answer: Yes, but exact analogs are rare. Most projects use Kubernetes as a deployment platform for network functions rather than making the cluster itself a network device.

Datum Q1 2026 — Top 10 Accomplishments

Activity across datum-cloud/enhancements, datum-cloud/infra, and datum-cloud/network-services-operator. Period: January 1 – March 10, 2026.

1. Activity Service — Full Stack to Production

The activity system went from an idea to a fully deployed production service. Work spanned the activity-apiserver (sharing the etcd cluster, infra#1875), activity-processor with NATS mTLS (infra#1584, infra#1587), a ClickHouse full-text index fix for v26.1 (infra#1885), the activity-ui (infra#1581), ActivityPolicy support wired into dns-operator ([infra#1832](https://github.com

Datum Cloud Authoritative DNS Service: Research Report

1. Overview

The authoritative DNS service solves two distinct but related problems:

User-facing DNS management: Datum Cloud customers own domain names (e.g., example.com) and want Datum to serve authoritative DNS for them. Users create a Domain resource to claim ownership, a DNSZone resource to declare a hosted zone, and DNSRecordSet resources to manage records. Datum's infrastructure then serves live DNS responses for those zones.
