  1. 1Objects are immutable and addressed by key over HTTP, optimized for scale and durability rather than POSIX semantics
  2. 2It supports in-place byte-level random writes to any offset of an object without rewriting the whole object
  3. 3It can only be mounted as a root filesystem on a single host and cannot be accessed over the network at all
  4. 4It has no durability guarantees whatsoever and is expected to lose objects whenever a single underlying disk fails
