RIs are like discount coupon booklets • Each RI gives one coupon per hour per instance being reserved over the term of the RI (e.g. a 1 year RI provides 24*365 coupons) • The coupon provides a discount in exchange for commitment • Each individual coupon expires at the end of each hour • RIs are a financial construct/layer on top of your AWS infrastructure RI coupon

16. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved. RIs are best used for Always-On instances (can still be used to save for non-always on) Commitment level 1 year (approx. payback 7-8 months) 3 year (approx. payback 12-18 months) AWS services offering RIs Amazon EC2 & EC2 Hosts Amazon RDS Amazon Redshift Amazon ElastiCache Amazon DynamoDB (not quite RI) Amazon CloudFront (not quite RI)

Understanding Instance Size Flexibility • Effective March 1, your existing Regional RIs are even more flexible! • All Regional Linux/UNIX RIs with shared tenancy now apply to all sizes of instances within an instance family and AWS region. • E.g. 1 m4.xlarge RI can apply to: 2 m4.large instances or ½ a m4.2xlarge instance

24. © 2017, Amazon Web Services, Inc. or its Affiliates. All rights reserved. How do I purchase Reserved Instances? 1. Ask your account manager for a reserved instance recommendation report 2.
