Decentralized Service Deployment for Collaborative Environments

In this paper we present the design of a system which allows service deployment in a small-sized group of computers distributed through the Internet. These groups are formed by users who share a common interest, and voluntarily yield their own resources for the achievement of the collaborative activities of the group. Having enough resources contributed by the members of the group, our system guarantees service availability and the fact that the deployment and execution of the services is carried out using only the resources of the group. This management is done in a completely decentralized manner, and the system is self-organized in the presence of component connections, disconnections and failures. We demonstrate its validity through the implementation of a prototype and the execution of some tests, which allow us to guarantee that the system is self-organized, always reaching a consistent state
