Reserved Instances and Savings Plans are AWS forward contracts that provide discount rewards in exchange for the lock-in risk of using specific services or spending an agreed amount over a 1 or 3 year term.
We combine the different RI & SP types and options to access the highest 3 year discount rates without creating large, fixed, long-term liabilities for future cloud use. As a result we can confidently cover high proportions of your usage with discounts knowing that we can adjust commitments as needed to adapt to usage changes and avoid wastage.
