This is the wildest part. One company that is proving all the "why does <company> need 10000 engineers?" takes true.
AWS/GCP/Azure manage physical data centers across the globe, and includes hundreds of services/offerings on each platform.
Additionally, critical industries (hospitals, banks, airlines) often rely on these companies to be available/resilient at all times. Thus the need for increased global workforce. OF on the other hand, nobody is going to die if they can’t access the feet pics they bought for a few minutes or days.
You are not comparing the same companies.
