Embodiments relate to information technology resource management and scaling. According to one aspect, an upcoming event impacting an application operating on one or more resources is identified. A workload on the application is predicted based on the upcoming event identified and historical data about a previous event having similarity with the upcoming event. The prediction is performed using a predefined rule. A number of resources required to process the predicted workload is ascertained using a past scaling history of the application. The resources are scaled based on the ascertained number of said resources determined before the occurrence of the event.
