the whole "RIs or savings plans?" decision routes in two questions.
is it redshift or opensearch? → reserved node / reserved instance. no savings plan exists. done. is it another managed database — rds, aurora, elasticache, dynamodb and the rest? → database savings plan, 1-year no upfront, for steady-state.
otherwise it's ec2/fargate/lambda: compute SP for flexibility, ec2 instance SP for the deepest rate, a reserved instance only if you need a capacity guarantee in an AZ or a resale exit. everything else → compute SP, the safe default.
