Choose Ceph.

What Actually Matters
No fluff — just the differences that affect your decision
Ceph is open source (LGPL-2.1). Amazon S3 isn't. You can fork it, audit it, host it yourself — no permission needed. That matters.
Ceph dominates with 17.1k GitHub stars vs 0. Bigger community = more plugins, more answers on Stack Overflow, faster bug fixes.
Ceph is built in C++ — you can read the source, contribute, or fork it. Amazon S3 is closed-source, so you're trusting their engineering.
Try both — most offer free tiers. The right pick depends on your stack size, team, and tolerance for DevOps.
