This project aims to provide an easy to use, self-organising multi-master caching layer for various cloud stoarge backends, e.g. S3. It combines functionality of a simple object storage with added robustness of cross-node journal synchronisation, object replication and cluster auto-discovery. We know that Amazon S3 has proven to be fast and reliable, a PaaS solution that acts like a backbone for many business applications. But the cost of service may become too high depending on your usage patterns, for example, if your application runs in your own datacenter, then the file transfer costs will skyrocket. Also request frequency has its limits.
