- 38. @cloudability Understanding Modifications Follow the money ๏ There is no cost for modifications as instance types within a family are equally divisible ๏ After a modification your original reservation is retired, and“new”reservations are created with the same end date

- 45. @cloudability Modification Recommendations Recap ๏ Only reservations for instances with Linux OS can have instance type modified ๏ All reservations can be modified for Availability Zone and Network ๏ Reservations cannot be moved between accounts
- 46. @cloudability Modification Recommendations Strategy ๏ Modifications help align RIs to infrastructure and de-risk RI purchases for instances in a family ๏ First check if existing RIs apply to instances in other accounts if capacity is not a concern ๏ Optimize modifications around: - Moving reservations to a different AZ - Merging smaller instances into larger instances - As a last step break reservations apart
