Platform for online collaboration and e-learning in open source Distributed Cloud systems

In this paper we present the way in which SlapOS is used to run an online collaboration and e-learning platform in the cloud. This will include: chat, sharing document, voice, video and calendar scheduling. SlapOS is the first open source operating system for Distributed Cloud Computing. SlapOS is based on a grid computing daemon - called slapgrid - which is capable of installing any software on a PC and instantiate any number of processes of potentially infinite duration of any installed software. Slapgrid daemon receives requests from a central scheduler - the SlapOS Master - which collects back accounting information from each process. SlapOS Master follows an Enterprise Resource Planning (ERP) model to handle at the same time process allocation optimization and billing.
