CunoFS: Is POSIX Outdated in the Cloud Era?
POSIX is an established standard that developers know how to interact with, providing them with a less complicated and less error-prone development process. Lots of existing software is built on the POSIX filesystem paradigm, ready to run in any environment that supports it or be integrated into new toolchains to reduce overall development time. POSIX stays relevant not because of bleeding-edge features, but because developers like its reliability — they only use object storage APIs because they have to.
