A new low-cost could service (1/4th of AWS price) could potentially become an extremely cost effective storage asset for multiple bussinesses if it features an interface which is easy to integrate with their existing infrastructure.
Together with an open-source filesystem interface development team, we have designed many variants of a solution which would provide consistency and reliability in multiple endpoints using the same storage bucket.
The analysis has concluded that current feature setof the cloud in question does not allow for implementation of such a filesystem with acceptable performance characteristics. Using an additional service for locking would increase price too much and would potentially compromise security.
Additional features were requested from the could operator to enable implementation of a high-performance design.
