Presentation

ownCloud has traditionally used the database to store metadata including the file hierarchy, shares, comments and tags.
Keeping this database metadata in sync with the actual filesystem becomes challenging when requests time out or fail for other reasons such as stale locks, partially traversed trees, or changes on storages that are not propagated, ultimately leading to filecache corruptions....

6. On the way to OCM 1.0, a first stable version ready for mass adoption

Synchronization/Sharing Technology & Research

Presentation

During the last year Nextcloud took huge efforts to implement the Open Cloud Mesh API. We see this as a important building block to bring Cloud Federation to a large group of users in a vendor neutral way. As the principal authors of the concept of Cloud Federation and driving force behind it, we looked not only on what we have but also on what we want to achieve in the future. This led to...

48. A journey to the mesh : microservices-based sync and share using gRPC and Protobuf

Synchronization/Sharing Technology & Research

Presentation

CERNBox is a multipetabyte-scale sync and share platform at CERN, storing close to 7 PB of data for more than 16K users. Over time we have identified different improvement points to increase development agility and maintenance costs for running the service. Last year we have evolved the architecture of the service from a monolithic stack to a decentralised model based on micro-services. This...

31. Is “zero-knowledge” privacy achievable in the distributed cloud? An in-depth analysis of encryption architecture of Cubbit’s sync&share service.

Mr Marco Moschettini (Cubbit)

Synchronization/Sharing Technology & Research

Presentation

Cubbit is a hybrid distributed cloud where a central “coordinator” server organizes the resources of a “swarm” of peer-to-peer interacting devices to offer performant and encrypted cloud services. One of Cubbit’s core principles is “privacy by design”, meaning that no third party, including the coordinator server, can access the content of the users’ files.

The usual paradigm of encrypted...
