SbQA is a Satisfaction-based Query Allocation framework for distributed environments where consumers and providers are autonomous and have special interests towards providers and queries, respectively. We experimentally demonstrated that it ensures good system performances while satisfying consumers and providers. Hence, SbQA can scale-up in these environments by preserving the total system capacity, i.e. the aggregate capacity of all providers. SbQA is used in the Strep Grid4All project as the basis to perform selection of services proposed by market-places as well as altruist contributors. SbQA is implemented in Java.
