Gets recommendations for which reservations to purchase. These recommendations could help you reduce your costs. Reservations provide a discounted hourly rate (up to 75%) compared to On-Demand pricing.
AWS generates your recommendations by identifying your On-Demand usage during a specific time period and collecting your usage into categories that are eligible for a reservation. After AWS has these categories, it simulates every combination of reservations in each category of usage to identify the best number of each type of RI to purchase to maximize your estimated savings.
For example, AWS automatically aggregates your EC2 Linux, shared tenancy, and c4 family
usage in the US West (Oregon) Region and recommends that you buy size-flexible regional
reservations to apply to the c4 family usage. AWS recommends the smallest size instance
in an instance family. This makes it easier to purchase a size-flexible RI. AWS also
shows the equal number of normalized units so that you can purchase any instance size
that you want. For this example, your RI recommendation would be for
because that is the smallest size instance in the c4 instance family.
For .NET Core and PCL this operation is only available in asynchronous form. Please refer to GetReservationPurchaseRecommendationAsync.
