Cache pricing
ISR and Runtime Cache 8 KB read and write units.
ISR and Runtime Cache share Cache Read Units and Cache Write Units. A unit is 8 KB: ceil(bytes / 8192). A 0-byte miss is 0 units.
Regional multipliers apply after the 8 KB conversion. Remaining cache units in the dashboard are base-region-equivalent.
Included allowances and on-demand ranges are in What each meter counts.
Image Optimization cache hits are not cache-write units and are not Image Transformations. See Image Optimization pricing and Runtime Cache.
