Cost Model of Data Set Storage in the Cloud

In this section, we present our new cost model of data set storage in the cloud. Specifically, Section 4.1 introduces a classification of application data in the cloud and further expresses the scope of this research. Section 4.2 introduces data provenance and describes the concept of data dependency graph, which is used to depict the data dependencies in the cloud. Based on Sections 4.1 and 4.2, in Section 4.3 we describe the new cost model and its important attributes in detail.

The cost model that has been utilised in our work is presented in [87,89,90,91].

4.1 Classification of Application Data in the Cloud

In general, there are two types of data stored in the cloud storage – original data and ...
