I laugh at some of the "Independent studies" that vendors release, for example the blog posted on the Broadcom site about comparison over OpenShift:
https://blogs.vmware.com/cloud-foundation/2024/12/03/vmware-vsphere-8-supports-1-5-times-more-vms-and-delivers-62-more-data-transactions-than-red-hat-openshift-virtualization/
The data was gathered by Principled Technology (never heard of it):
https://www.principledtechnologies.com/Broadcom/vSphere-8-U3-VM-density-comparison-1024.pdf
All the way at the bottom: "This project was commissioned by Broadcom."
With all that said, there may be some truth to some of this content, but come on. By no means am I downplaying some of the major vendors that do independent studies such as Gartner, Forrester, etc.
