In modern cloud- and fog-based architecture, the exchange, management, continued discovery, and provision of data are key concerns. This article presents an architecture for a Data as a Service (DaaS) marketplace, hosted in a cloud environment and supporting cloud-based applications. The architecture includes a storage management engine, a monitoring component, and a data discovery service. The results show that the proposed system outperforms the ElasticSearch queries while the semantic enhancement of the process adds relevant data to the results. Finally, the paper shows that the real-time scaling provided keeps the QoS requirements in check by decreasing the latency of the data requests, by adding new servers to the data storage cluster as needed in less than 10 seconds.
