Interconnected Private Clouds for Universities and Researchers

OpenCloudMesh is a joint international initiative under the umbrella of the GÉANT Association that is built on ownCloud’s open Federated Cloud sharing application programming interface (API) taking Universal File Access beyond the borders of individual Clouds and into a globally interconnected mesh of research clouds - without sacrificing any of the advantages in privacy, control and security an on-premises cloud provides. OpenCloudMesh provides a common file access layer across an organization and across globally interconnected organizations, whether the data resides on internal servers, on object storage, in applications like SharePoint or Jive, other ownClouds, or even external cloud systems such as Dropbox and Google (syncing them to desktops or mobile apps, making them available offline).

Community effort

A collaborative project was established under the umbrella of GÉANT called the OpenCloudMesh project on 22 October 2015. The kick-off meeting was held in Vienna, Austria.

The project is co-managed by Christian Schmitz (ownCloud), Jakub Moscicki (CERN) and Peter Szegedi (GÉANT).

The collaborative project is fully open to any participation and in-kind contributions. Interested parties can subscribe to the mailing list at:



  • Around early 2012, TF-Storage participants started to actively look into data storage software platforms in order to provide on-premise file-based sync&share (aka. Dropbox-like) services to their constituencies.
    • Some NRENs even ventured into the development of a proof-of-concept tool called the Trusted Cloud Drive (TCD) under TERENA
  • By mid 2013, ownCloud appeared to be the most promising one with a growing open-source development community behind.
  • In December 2013, the GÉANT Association (formerly known as TERENA) and ownCloud Inc. made an agreement that serves to facilitate the desire of various National Research and Education Networking organisations (NRENs) to introduce services based on ownCloud technology and/or to offer the technology to their constituencies.
  • As part of this collaboration effort, in January 2015, ownCloud initiated an idea (aka. OpenCloudMesh) to interconnect the individual on-premise private cloud domains at the server side in order to provide federated sharing and syncing functionality between the different administrative domains.
