Google mostly runs their own data centers. Amazon mostly rents space in commercial data centers with lots of different companies. Aws is probably pretty secure but likely less physically secure compared to Google if you get into the nitty gritty details.

This is false. Aws builds and operates their own data centers. The design and architecture of their data centers are highly standardized and an enormous amount of the build is fully automated. When they do lease they lease just a basic power and fiber build and they build their data center ontop of the base. Given how much custom equipment they run at the data center level it would be impractical to do anything that was collocated. But most data centers for aws, especially in Virginia, are on Amazon owned land. As far as I am aware the only collocations are in the satellite zones, outposts, and in peering locations.
