Cost savings on AWS

AWS recently introduced the “Compute Savings Plan” for Lambda. It allows for 12% to 17% discount on the expenses.

($1 per hour is a LOT of Lambda usage though so probably your actual situation will not benefit this much).

Use cases could be: resizing images, partially hiding some data based on requester identity or adding headers from another datasource.
