There is no such thing as “Vanilla Kubernetes”
The document discusses the misconceptions surrounding 'vanilla' Kubernetes, emphasizing that all vendor distributions differ significantly and that there's no true 'vanilla' version. It highlights the high costs associated with building app platforms and the necessity of community and professional support for Kubernetes usage. Additionally, it outlines the importance of certified Kubernetes conformance for ensuring interoperability across various platforms.

KUBERNETES CONFORMANCE 18 Interoperability atthe API “The new Certified Kubernetes Conformance Program gives enterprise organizations the confidence that workloads that run on any Certified Kubernetes Distribution or Platform will work correctly on any other version,” said Dan Kohn, Executive Director, Cloud Native Computing Foundation. “The interoperability that this program ensures is essential to Kubernetes meeting its promise of offering a single open source software project supported by many vendors that can deploy on any public, private or hybrid cloud.” One of the goals of the project has always been consistency and portability. Kubernetes sits on top of the infrastructure and enables you to describe your workload in a common format. Kubernetes makes it easy to move workloads from one place to another, or combine disjointed environments with a shared control plane. This program gives end users the confidence that when they use a Certified Kubernetes product they can rely on a high level of common functionality. It gives Independent Software Vendors (ISVs) confidence that if their customer is using a Certified Kubernetes platform that their software will behave as expected. * https://github.com/cncf/k8s-conformance
