Our Journey from Ubuntu Server to Ubuntu Core
summary
Company moves 3001 Dell gateways and a new Apex hardware target from Ubuntu Server 16.04 to Ubuntu Core to get snap-based transactional updates, confined services and A/B fallback. The team engages Canonical for board enablement and a private brand store, migrates roughly 650 gateways in the field in 2020 and now runs ~340 devices on Core. Built a consolidated backend called dmscore (Device Management System) (snapd agent, NATS auth, Terraform, golang-migrate) to control snaps, tracks, auto-registration and rollbacks.
