Seafile (http://seafile.com) is an open source cloud storage system. Seafile is already used by over 100 thousand users worldwide.

Seafile provides file syncing, sharing and team collaboration features. It is designed with to make file collaboration for teams more efficient.

The core technology of Seafile is an application-level file system, built on top of object storage systems. The architecture can scale out horizontally by adding more servers. It supports S3, Swift or Ceph/RADOS as storage back end. The file syncing algorithm is designed to be efficient and reliable.

In this talk, we will present:

* Seafile's features, including file syncing, sharing, and team collaboration * Seafile's architecture and technology, including file system design, cluster, and syncing algorithm.
