  EC2 Instance Savings Plans provide the lowest prices, offering savings up to 72% in exchange for commitment to usage of individual instance families in a region (e.g. M5 usage in N. Virginia). This automatically reduces your cost on the selected instance family in that region regardless of AZ, size, OS or tenancy. ***EC2 Instance Savings Plans give you the flexibility to change your usage between instances within a family in that region.*** For example, you can move from c5.xlarge running Windows to c5.2xlarge running Linux and automatically benefit from the Savings Plans prices. https://aws.amazon.com/savingsplans/faq/#:~:text=EC2%20Instance%20Savings%20Plans%20give,from%20the%20Savings%20Plans%20prices.
