Forecasting Scientific Cloud Workflow Activity Duration Intervals

As discussed in Chapter 2, workflow activity duration is one of the basic elements in the temporal consistency model, and thus its accuracy is critical for the effectiveness of temporal verification and all the other related components such as temporal checkpoint selection and temporal violation handling. Therefore, an accurate forecasting strategy is required to predict cloud workflow activity durations. However, it is not a trivial issue due to the dynamic nature of cloud computing environments. In this chapter, we present a statistical time-series-based forecasting strategy for scientific cloud workflow activity duration intervals. The comparison results demonstrate that our ...
