Yep there is so much overhead to making things decentralized. Take a look at filecoin sealing. Its a super cool system with a bunch of fun cryptography and math, but generating the proofs requires a lot of time and compute power and adds a whole bunch of restrictions to how you can upload data.

If you really, really, want to say your storage is decentralized, use it, but S3 is a 1000x simpler.
