As an ArcGIS Online administrator, one of your primary responsibilities is monitoring and managing credit consumption in your organization. Credits are the currency of ArcGIS. They are consumed for specific transactions and various types of storage, including feature storage, imagery storage, and file storage.
Storage credits are consumed when organization members create and store content items such as maps, apps, scenes, and layers. If your organization’s storage credit consumption is higher than you and other stakeholders would like, you may be looking for ways to reduce it.

This recently published blog article outlines practical strategies for managing storage credits in your organization. It also describes how ArcGIS Online calculates storage credits and how to identify and manage the content items that are incurring the highest storage credit costs.
