Systems and methods scale an instance group of a computing platform by determining whether to scale up or down the instance group by using historical data from prior jobs wherein the historical data includes one or more of: a data set size used in a prior related job and a code version for a prior related job. The systems and methods also scale the instance group up or down based on the determination. In some examples, systems and methods scale an instance group of a computing platform by determining whether to scale up or down the instance group by at least evaluating on-demand job request data for resource units (RUs), observing current job state data, and predicting resource unit need using historical data from prior related job executions. The systems and methods scale the instance group up or down based on the determination.
