Compute Savings Plans and Reserved Instances
Compute Savings Plans are a flexible pricing model that offers low prices, just like Amazon EC2 Reserved Instances (RI), but with added flexibility. With Savings Plans, you can reduce your bill by committing to a consistent amount of compute usage (measured in $/hour), instead of specific instance configurations. Savings Plans give you the flexibility to use the compute option that best suits your needs at low prices, without having to perform exchanges or modifications.
Compute Savings Plans provide savings up to 66 percent off On-Demand, similar to Convertible RIs. Compute Savings Plans automatically reduce your cost on EC2 instance usage, Fargate, and Lambda. EC2 Instance Savings Plans offer savings up to 72 percent off of On-Demand, similar to Standard RIs. They also automatically save you money on any instance usage within a given EC2 instance family in your Region of choice. For more information, see Savings Plans types.
