How does PrEstoCloud address the constraint of data locality?

This Big Data constraint is more important when data and computing are geographically dispersed. Data locality means moving computation closer to the data source. In some cases, computational tasks are sent to resources where the data resides. According to the PrEstoCloud solution, data-intensive workloads can be decomposed into loosely-coupled parallel tasks. As a consequence, the utilisation of resources and scheduling can be improved.
