Gets recommendations for reservation purchases. These recommendations might help you to reduce your costs. Reservations provide a discounted hourly rate (up to 75%) compared to On-Demand pricing.
Amazon Web Services 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 Amazon Web Services has these categories, it simulates every combination of reservations in each category of usage to identify the best number of each type of Reserved Instance (RI) to purchase to maximize your estimated savings.
For example, Amazon Web Services automatically aggregates your Amazon 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. Amazon Web
Services recommends the smallest size instance in an instance family. This makes it
easier to purchase a size-flexible Reserved Instance (RI). Amazon Web Services also
shows the equal number of normalized units. This way, you can purchase any instance
size that you want. For this example, your RI recommendation is for c4.large
because that is the smallest size instance in the c4 instance family.
For .NET Core this operation is only available in asynchronous form. Please refer to GetReservationPurchaseRecommendationAsync.
