Abstract: Real-time workload for an application is converted into a capacity unit value. A trained machine-learning model receives the capacity unit data as input and generates a prediction of capacity usage for the future. Based on the prediction, additional clusters may be allocated for the application. A dataset for use in predicting future capacity unit usage by an application may be classified into two categories. A first category comprises time series data. A second category comprises service types, target user types, and other attributes with discrete characteristics. Discrete attributes are incorporated into a wide section and time-series data is integrated into a deep section. A wide and deep model combines results from the wide section and the deep section to generate a prediction of capacity units used by the application in future time periods. In response, an allocation system allocates a corresponding number of clusters.
