What companies use aws

Question

Hi guys. So I was actually trying to bring my personal blogging website onto the cloud. For this, I checked out the costs and it didn't make sense for me to opt for cloud as my website doesn't even get that much traffic. So then, a question came to my mind. What kind of companies use cloud? A big government organization using cloud makes sense but if I had to ask you to compare it with some brand names, would you be able to tell which companies use cloud or not?
