I'm a big believer in Kubernetes, but was amazed to read that Mercedes-Benz recently shared they operate over 900 Kubernetes clusters - https://www.infoworld.com/article/3664052/why-mercedes-benz-runs-on-900-kubernetes-clusters.html

Excluding hosting providers (e.g. AWS for EKS, Google for GKE, etc) how many Kubernetes clusters does your company operate, and what information can you share about them?

Example:

- How many k8s clusters do you have?

- How many VMs in total or typical cluster size?

- How many containers do you run?

- Why so many? (e.g. lots of customers, lots of internal developers, cell-based architecture, etc)

- Do you run on EKS, GKE, AKS, OpenShift, bare metal etc?

- How do you manage them (Rancher, Crossplane, Terraform, etc)?

- Is the platform growing or shrinking?

- What's the split between development & production?

- If you're able to share the company name, great... if not, can you explain the space you're in (e.g. SaaS provider, AdTech, etc)

- For those at scale (more than 500), what have you found that a) works well b) doesn't work well?

To get things started, here's some information I can share about my company in relation to the 2021 CNCF annual survey...

https://www.cncf.io/reports/cncf-annual-survey-2021/ (about ~2,100 responses)

About 6% of respondents had more than 5,000 nodes (we have over 50,000 - over 10x that)

About 9% of respondents ran more than 5,000 containers (we have over 500,000 - over 100x that)

About 6% of respondents ran more than 50 k8s clusters (we have over 2,000 - over 40x that)

Thanks for sharing!
