Afaik cluster administration is pretty complicated. They had a pretty big internal deploy at JP Morgan Chase and I was under the impression other Fortune 50s had internal deployments but it takes a dedicated team to run. I think nowadays building on top of Kubernetes has completely eclipsed the CF stack. There's a buildpacks CNCF incubator and you can get k8s pretty close with different tools/abstractions.
