It's more fun to try and figure out where the bottleneck would be. Back in the early 00s I hosted websites on my local off the shelf Dell desktop on a cable internet connection. Cloud computing wasn't really a thing and I didn't know better / have much better options (eventually I did migrate to some webhost bundled with the DNS registar). For the longest time network bandwidth was my limiting factor. I remember finally upgrading my connection, NIC, etc. to the point where it was actually harddrive write speed that was the bottleneck. Probably depends on your application but harddrive I/O does seem like a likely limiting factor to me today.
