Committed Use Discount (CUD)
A 1- or 3-year commitment for a large discount — resource-based CUDs are tied to a region and machine family; flexible CUDs trade some discount for portability.
A resource-based Committed Use Discount commits you to a quantity of vCPUs and memory in a region and machine family for one or three years, in exchange for a steep discount — roughly up to 37% for one year and 55% for three (higher on memory-optimized). Spend-based (flexible) CUDs commit to an hourly dollar spend that flexes across series, at a smaller discount (about 28% / 46%).
This explorer shows the resource-based 1-year and 3-year CUD rates, composed per machine. They are the deepest committed discounts for a known, steady workload.
FAQ
What is the difference between resource-based and flexible CUDs?
Resource-based CUDs commit to specific vCPUs/memory in one family and region for the biggest discount. Flexible (spend-based) CUDs commit to a dollar-per-hour spend that applies across families for more portability but a smaller discount.
