SESSION ABSTRACT

Decentralized Cloud was introduced in 2010 (http://bit.ly/SWVQlw). It relies on a an massively decentralized infrastructure where servers are located in thousands of homes or offices rather than in a few data centers. This recent evolution of Cloud Computing provides in higher resiliency at lower cost.

In 2012, government has adopted decentralized Cloud to serve 30,000 users (http://bit.ly/Sm5e5P). It is the first large scale adoption of Decentralized Cloud. The goal of this presentation is to introduce key factors which have lead to this decision and discuss the merits of Decentralized Cloud vs. Centralized Cloud. The presentation will be held jointly by Stéphane Konan, head of information systems at the Ministry of Interior, Ivory Coast and Jean-Paul Smets, CEO of Nexedi.

The first factor for the adoption of Decentralized Cloud is resiliency. Decentralized Cloud acts here as a backup for Sovereign Cloud. In case of force majeur event such as a natural disaster or a terrorist attack which affects data centers, hundreds of small servers spread all over the world can act as a disaster recovery infrastructure.

The second factor for the adoption of Decentralized Cloud is cost. Being based on a container technology which is more efficient than virtualization, Decentralized Cloud can host more applications and more users at the same cost. Automated data distribution isused in Decentralized Cloud to compensate for the lack of Storage Area Network. and to achieve further cost reduction.

A third factor is resource sharing. Unused Cloud resources can be shared through the federation protocol at the core of Decentralized Cloud, which also involves Capacity trading and monetization.

An example of imlementation of Zimbra messaging server for 30,000 through a distributed storage will be demonstrated, based on SlapOS open source Cloud technology and devops recipes written in open source "buildout" language. The equivalent architecture based on Centralized Cloud, SAN and virtualization will compared.

Overall, Decentralized Cloud has now become a serious alternative to centralized private clouds.
