Abstract
Cloud computing follows a layered architecture where each layer targets a particular domain of end users. In such a layered architecture, provenance (the metadata that describes the derivation history of the object) of the individual layers is of significant importance to establish trust and authenticity. In a typical Cloud environment, each layer provides important provenance information which usually targets a particular domain of clients e.g. Cloud provider uses infrastructure provenance to track resource utilization. In the case of aggregated provenance, it becomes challenging to manage provenance information because of the relationships that exist within Cloud layers and the creator object. The existing techniques and systems to address provenance in Clouds usually work at a single layer of abstraction. These systems, however, fail to answer questions which require aggregated provenance from the individual layers. In this paper, we reason about the need of aggregated provenance, its significance and a proposed solution which works at different layers of abstraction for the management of provenance data. We also present a case study to signify the importance and necessity of collective provenance for various application domains.
