I'm curious if anyone has seen any reports or surveys that indicate what percentage of enterprises are using different versions of Kubernetes. I know it's tricky to have accurate public data, but it seems like managed cloud providers like EKS, GKE, and AKS could run some sort of report on the clusters they manage. I'm particularly interested in how many organizations are still running older versions, like anything before v1.29. A broader overview, such as something from the CNCF about the state of the industry, would also be appreciated.

A lot of companies stick to outdated software, like RHEL 5. It’s important to stay within a couple of minor releases of the current version. Personally, I keep most of my infrastructure on 1.33, with a few on 1.32.
The most detailed report I've found is based on data from Censys, compiled by Rory McCune. It gives a good overview of version distribution trends that might help you understand where things stand.
If you're on anything older than 1.31, you're really taking a risk. Kubernetes has a short support window, so keeping updated is crucial to avoid vulnerabilities and support issues.
Yes, there are reports about Kubernetes usage. Typically, businesses lag by at least two versions behind the latest due to caution. That’s why cloud providers often create LTS (Long Term Support) versions.
