Case Study: LY Corporation scales Kubernetes to 1,300+ clusters with CNCF

LY Corporation scales Kubernetes to 1,300+ clusters with Cloud Native Computing Foundation

LY Corporation, a Tokyo-based technology company, faced significant challenges scaling its infrastructure efficiently and securely on its private cloud. Manual provisioning took over a week, node recovery was slow, and maintenance risked service disruption, all of which limited business velocity. To overcome these scaling and automation hurdles, they partnered with the Cloud Native Computing Foundation (CNCF) ecosystem, utilizing Kubernetes.

By leveraging Kubernetes Custom Resource Definitions (CRDs) and custom controllers as an infrastructure control plane on their OpenStack-based private cloud, the vendor Cloud Native Computing Foundation (CNCF) enabled a fully automated solution. This allowed LY Corporation to scale from 5 to over 1,300 clusters and 40,000+ nodes. The results were transformative: provisioning time was cut from weeks to hours, manual node recovery was completely eliminated, and 15 engineers now reliably operate the entire hyperscale platform with zero-downtime upgrades.
