Recently, I have found out about Microsoft Cybersecurity Reference Architecture. It shows how Microsoft products can fit into an existing company's network and policy setup, however it is quite generic.
I am looking for something similar to that, but just an example, reference network diagram from a known tech company or mentioned in a scientific paper, such as the "logical diagram" on the left hand side of the image below. Previously, I have come across "An analysis of cyber reference architectures", but again, the diagrams mostly feature lists of things (policies, security awareness, physical and non-physical measures etc.), as opposed to those lists applied to an example diagram.
In short: Are there any example/use case/reference 'secure' network diagrams, such as the one on the left above, that have been released from a well-known source?
EDIT: All of the answers are great, thank you for taking the time to answer! I am struggling to accept one because they both provide really good perspective on the matter.
