Kumori Labo holds both the Kubestronaut and Golden Kubestronaut certifications: two of the most prestigious distinctions in the Kubernetes ecosystem, by the Cloud Native Computing Foundation (CNCF) and the Linux Foundation.
The Kubestronaut title requires passing all five core Kubernetes certifications (CKA, CKAD, CKS, KCNA, and KCSA), kept active simultaneously, and is held by only around 1,500 professionals worldwide. The Golden Kubestronaut goes further, requiring all 16 CNCF and Linux Foundation certifications across Kubernetes, security, observability, networking, GitOps, and platform engineering.
When you work with Kumori Labo, you get engineers who know Kubernetes inside out, not just in theory, but across every layer of the stack.
