Discussion mailing list ( has been set up for Phase ii. Pilot participants can subscribe to the list here.

How to participate


There are three ways to participate.

  • Bring your test users and try out the TERENA installation of the service. The platform is federated, all the national federations are connected as well as the guest federations such us Google, Facebook, etc. So, if you have e.g., a Google account you can try this service out. Please do note that, due to service restrictions, all the actual test users must be whitelisted. For the procedure to be whitelisted please contact Peter Szegedi (


  • Get access to the TERENA installation and go to

  • Attach your own storage back-end to the platform installed at TERENA Offices. Currently, the service uses a local file system at TERENA Offices and it has the possibility to store encrypted data in the Amazon S3 cloud. If you want to connect your own storage back-end, you have to develop the bridge between the cloud broker platform and your data storage facility. For the interface/protocol description and detailed technical information please participate in the mailing list discussion.

    Check out the preliminary service delivery scenarios.

  • Get familiar with the code. The code is open source written in Scala and runs on top of the JVM. You can get familiar with the code step by step. We provide a single downloadable VM image, we also provide the clone of the TERENA system installation (on 2 VMs, with federated access), and you can go to Github for the source code and documentation. Use the Google group for questions.

Get familiar with the code


The aim is to gradually build up a community with developers who will eventually become "co-owners" of the code. It is expected that the potential co-owners' organisations contribute to the code maintenance and development with man-power and/or money. There is a three-step approach to get familiar with the code (it is also a kind of selection process).

STEP 0) Try the service out (the TERENA installation) - Your account must be whitelistedwhite-listed.

STEP 1) Downloadable development VMware images (Metadata store, WebDAV server, Website) - Ubuntu 12.04 LTS Server with openJDK 6, MySQL, cadaver (ZIP file) and Readme (TXT file).

STEP 2) Source code and documentation is available on Github under Apache Licenses, Version 2.0. There is limited free support via the Google group. Pilot participants (PSNC, BELNET) also contribute to an Installation Guide. TERENA has its own Github space where the Trusted Cloud Drive project is forked (temporarily) and Github users (developers) can be added to the team



The full documentation is available at Github (main branch) Wiki.

Will be installed in multiple virtual servers. Performance tests will be done.


Installed on a) one single VM b) multiple VMs (see the Installation Guides)

Next on the agenda is performance testing. For this I will try to get the data when using 1-3 WebDAV daemon nodes.

I will try to scale the WebDAV daemon, put a load balancer before the nodes and do some performance tests.

Performance tests are done! Results are here.

RNPGui Maluf


Working with prof. Roberto Samarone Araújo and prof. Jeroen Van de Graaf within a similar project, and we're planning to make a bridge between OpenStack Swift and TERENA cloud broker.

(lightbulb) OpenStack S3 API development at the back-end.

(question) Fortunately the aaws library is open source. So I got the code, changed the constant S3_HOSTNAME, regenerate the Constant.class and put it inside the jar, changed the /etc/rightfabric/config.txt to use storage  = s3, restart all services, but looks like it is using local filesystem instead of trying to make the s3 connection!

Am I doing something wrong?

(warning) Handy hint for using s3 libraries to connect to OpenStack Swift. A while back, AWS changed the way the S3 endpoints work. Previously, buckets lived at, whereas after the change they now live at a subdomain: For this reason, modifying some of the libraries and tools to work with OpenStack Swift's S3 endpoint (which doesn't do the DNS smarts) is not easily possible with current versions.

This may not be the issue you're experiencing, but if odd things are happening, keep it in mind.

  • Basic protocol is working (put. get, delete, etc.) Waiting for employee authorization to publish the code on Github.

OpenStack Java SDK was used for connecting the Swift installation and doing the back-end process to TCD. It is contributed to TERENA Github. TCD integration with RNP's OpenStack Swift based cloud storage infrastructure is planned.

Christos Loverdos

Installed on Pithos+

GRNET will be integrating the Trusted Cloud Drive with the Pithos+ storage service that we have developed. Christos has been working with GRNET on Okeanos, our overall cloud storage service, and more specifically on its accounting components, written in Scala. He is an expert in Scala.

(lightbulb)OpenStack / Pithos+ interface to the cloud broker platform.

  • The Pithos+ interface is in a very good shape and almost complete. I have stumbled across a few issues with the existing Cloud Drive codebase and I had sent a relevant email a while ago. Live demo of the Cloud Drive integration with GRNET's production Pithos+ service will be done at TF-Storage.

Integration is done, contributed to TERENA Github, demonstrated at TF-Storage

Praveen Misra 

I had been exploring different opportunities of collaborating on the cloud technologies and found interest in cloud pilot. Do let me know if its possible and feasible for us to get involved with this initiative.


João Pagaime (tick)

At this stage we looking for information for a possible more official commit in the future.

As far as the  reasons go, we already use filesender and are happy with it, and we  see interest from the community on storage services beyond commercial available services.

The planned contribution is to test the software,  set up a test storage backend and generally participate  on the initiative  (it's worth to mention that we don't have dedicated resources devoted for this. That is to say that we would have difficulty on doing resource hungry taks.

We're evaluating  installing the cloud platform at our location for experimental purposes (01/10/2012)

I have an idea about how this could work on the NREN (probably on a pilot), but I'm not sure about it's feasibility:

- can we have a central installation on the NREN (FCCN) and have the NREN institutions participate with the raw storage?

- if so, how would the NREN institutions make available the storage to the central installation? does it make sense to use, for instance, a gluster-fs? does the TERENA Trusted Cloud Drive already have some software module to do that?

theoretically we could configure special network conditions for the shared file-system within the NREN (20/11/2012)

Saying that, a scala driver that dispatches users to their "home institution" is indeed a very nice feature. Specially after a pilot phase, if things start to scale up.


Panos Louridas

Christos Loverdos

We are interested in participating, and our focus will be in the following item from the Phase II description: Attach your own storage back-end to the platform installed at TERENA Offices Specifically, to attach our own OpenStack-derived platform as a storage back-end.

Concerning GRNET, our efforts will focus on providing a bridge to connect from the GRNET storage service (Pithos+) to the cloud pilot. Right now the Cloud Pilot includes support for Amazon S3 and JClouds; we use an OpenStack compatible API, so we will be going for an OpenStack / Pithos+ interface to the cloud interface.

We might offer some test storage resources controlled by OpenStack Swift and/or plug into your system some WebDAV enabled storage.

In addition we might spend some hours on reviewing the code and/or penetration testing of your pilot installation.

SECURITY AUDIT; Our current plans regarding the local installation include:

- doing some stress / functional testing

- checking if your solution will work with S3-enabled OpenStack swift

- performing a security audit (I am adding Gerard and Pawel from security department in CC)

Recently, we constructed a cloud storage based on the OpenStack Swift. We took a look on the phase 2 webpage and noted that it is possible to integrate other clouds to the TERENA Trusted Cloud Drive.

We are interested in integrating our cloud to your solution. Thus, we would like to know what are the requisites for this.

We are interested for the following reason: Higher Education Users are increasinglgy increasingly asking for a cloud shared storage. I'm thinking about students, but also researchers and teaching staff may be interested in this. We are evaluating which solution could adress address the need of users best in the future. The TTCD is one possibility and I'm interested about the future developments in that project and the uptake of other NRENs of TTCD, how they see the place of a service based on the TTCD in their portfolio.

I am part of the Blue Brain Project, based at EPFL. Our long-term goal is to build a facility to help the worldwide community of neuroscientists work in the understanding of the brain and its processes.

My understanding of this second phase of the pilot is that will enable secure cloud-like sharing based on established federations and this sounds very interesting to me. Especially from the perspective of federations and how insightful could be for us in moving towards our long-term goals.

Università Roma TRE

Vincenzo Praturlon (tick) (tick)

We would be glad to join in, but first we need to discuss our involvement within our it staff. At the moment it is not clear what could be the outcome of a pilot in our university. It could be a federated service offered by us to the IDEM community, or it could be just an experimentation, possibly picked up by the federation itself for production (as happened for filesender). We are trying to have a clue of the efforts required to contribute to the project in a significant amount. The most reasonable target for a pilot within phase II would be to provide a small storage quota on Amazon to a few partner institutions and try to share some data. This would simplify, I guess, the "local" requirements. At that point we would be in position to decide whether to provide a back-end or pass it to the federation. I will try to scout this idea, but before "formally" committing I will have to put together some of the skills required.

In this second phase, we can initially collaborate providing feedback from our constituency test users and after attaching our own storage backend.

I would really like to collaborate in the project developing some part/s. I thought about connecting the pilot to a cdmi-proxy. Or develop the jcloud missing part. (On 10th October I will attend to an Adrian Cole's [jcloud founder] meeting in Barcelona) 

CESCA will provide the infrastructure needed to make a local installation of the cloud platform.
