Cost and Usage Dashboard prepares the data for analysis by creating a summary view of your cost and usage data by filtering out data, renaming fields, and adding calculated fields. It then stores the prepared data in Amazon QuickSight’s in-memory engine SPICE (Super-fast, Parallel, In-memory Calculation Engine), and selects the best type of visualizations for the selected fields. Your Cost and Usage Dashboard is updated once in every 24 hours.
