What is Cloudy

Cloudy [1] is a distribution based in Debian GNU/Linux [2] developed under the CLOMMUNITY european research project.[3]

This distribution, inspired in the idea of the old Guinux [4], facilitates the deployment and the management of cloud services[5], as well as sharing them. Particulary intended to the community network[6] users.


Prior to the general adoption of cloud services[5], users of Community Networks (CNs[6]) already shared or provided services and resources to the community, however, these users were only a minority. One of the reasons identified is the technological barrier. Before providing content, users willing to share information with the community have first to take care of the technical aspects such as the deployment of a server with a set of services.

In the past, users from the Guifi.net CN tried to overcome this problem by releasing a GNU/Linux distribution named Guinux [4], which provided end users an easy way of offering network services to the community (like HTTP proxy, DNS systems and MRTG graphic interfaces).

The key part of the distribution was a set of scripts[7] that automatised the configuration process. End users were only asked for a few parameters such as their e-mail address and the node identifier. Shortly after the distribution was made available the number of end users sharing resources proliferated.

According to that, it became clear that lowering (or removing) the technological entry barrier encouraged users to provide more services and share their resources with the community. To this end, one of the goals of the CLOMMUNITY [3] project is to release a GNU/Linux distribution, codenamed Cloudy, aimed at end users, to foster the transition and adoption of the Community Network cloud environment.


The Cloudy distributión is thought to satisfy the following requirements:

  1. Distribution: in order to foster services distribution amongst the Community Networks (CNs), a platform to publish and discover them is required. This way, service access does not depend on static networking deployments and is aware of the dynamically-changing conditions of CNs. The software chosen for service publishing and discovering is Avahi[8].
  2. Decentralisation: a common network layer is required to allow all CN cloud nodes to communicate with each other directly. A good way to build it is to create a virtual Layer 2 based on a VPN[9] service. Among the available options, Tinc VPN[10] has been chosen, as it fulfills all the requirements while being easy to configure and manage. To coordinate the devices with TincVPN, a tool to automate the system deployment has been developed as part of the project. This software, named Getinconf[11], takes care of the TincVPN configuration process and the exchange of keys with the rest of the cloud nodes.
  3. User-friendliness: to this end, a web-based management platform has been developed aimed to integrate all the installation and configuration steps for the cloud services enabled in the Cloudy distribution. A simple web interface[12] is available to the end user as an easy way of configure, administer and monitor the cloud services running in the node.
  4. Free, Libre, Open Source Software: the distribution has been based on Debian GNU/Linux[2]. Apart from being one of the most popular distributions and fulfilling all the technical requirements, it has been chosen because the Debian Social Contract[13] safeguards and guarantees that the software will always be open and free.
