Titre: SlapOS: a Slap into Cloud Monopolies Auteur : Jean-Paul Smets (Nexedi) Abstract : SlapOS is an operating for Cloud Computing designed to solve the growing concerns of lack of Freedom, loss of Privacy and weak Resilience of Cloud Monopolies. SlapOS is designed as a practical alternative so that everyone can create his own Cloud Computing business, help one each other and compete efficiently with Google, Amazon, Microsoft, Salesforce in a matter of hours or days. - Designed for Resilience : SlapOS can leverage the resources of multiple, independent providers of Computing power. Servers can be located in data centers, in offices or even at home. By combining independent providers of computing power, independent providers of electricity, of network, of storage, SlapOS is more resilient to natural disasters, political crisis, financial crisis, strikes or wars than traditional Cloud solutions managed by a single company. - Free Market Enabler : SlapOS is based on the idea, just like the Internet, that "intelligence should be at the end points". In SlapOS, it is the end point which takes the decision to change a provider or not in order to maximise quality of service. - Privacy Conscious : SlapOS is designed from the ground up to enourage data distribution and thus preserve user privacy. - Community Driven : SlapOS is based on mature, community driven open source software such as buildout, supervisord and ERP5. Everyone can also contribute his own server to the SlapOS community cloud and help eachother. - Technology Neutral : SlapOS is designed to run on the Cloud any software which depends on GNU glibc. Thus includes python, ruby, java, etc (long list) - Business Friendly : Unlike other initiatives for a Free Cloud, SlapOS recognizes that Cloud is not only about technology but also about business. For this purpose, SlapOS provides a business friendly, accounting and billing solution which can help any company become a Cloud Computing provider yet benefit from the support of the community. - Globally Educational : SlapOS is designed and developed in close relation with universities and research centers in Europe, Asia, America and Africa (soon Oceania). SlapOS community develops a practical curriculum to teach students "how to build scalable distributed systems which keep on working even when nothing works", using only open source software.
