get_reservation_purchase_recommendation
(**kwargs)¶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.

The specific service that you want recommendations for.
Use Expression
to filter in various Cost Explorer APIs.
Not all Expression
types are supported in each API. Refer to the documentation for each specific API to see what is supported.
There are two patterns:
CostCategories

, and Dimensions
.CostCategories
field to define a filter that acts on Cost Categories.Tags
field to define a filter that acts on Cost Allocation Tags.Dimensions
field to define a filter that acts on the DimensionValues.REGION==us-east-1 OR REGION==us-west-1
. For GetRightsizingRecommendation
, the Region is a full name (for example, REGION==US East (N. Virginia)
.Expression
for this example is as follows: { "Dimensions": { "Key": "REGION", "Values": [ "us-east-1", “us-west-1” ] } }
OR
when applying the filter.Expression
for this example is as follows: { "Dimensions": { "Key": "LINKED_ACCOUNT_NAME", "MatchOptions": [ "STARTS_WITH" ], "Values": [ "a" ] } }
Expression

.Expression
for this example is as follows: { "And": [ {"Or": [ {"Dimensions": { "Key": "REGION", "Values": [ "us-east-1", "us-west-1" ] }}, {"Tags": { "Key": "TagName", "Values": ["Value1"] } } ]}, {"Not": {"Dimensions": { "Key": "USAGE_TYPE", "Values": ["DataTransfer"] }}} ] }
Note
Because each Expression
can have only one operator, the service returns an error if more than one is specified. The following example shows an Expression
object that creates an error: { "And": [ ... ], "Dimensions": { "Key": "USAGE_TYPE", "Values": [ "DataTransfer" ] } }
The following is an example of the corresponding error message: "Expression has more than one roots. Only one root operator is allowed for each expression: And, Or, Not, Dimensions, Tags, CostCategories"
Note
For the GetRightsizingRecommendation
action, a combination of OR and NOT isn't supported. OR isn't supported between different dimensions, or dimensions and tags. NOT operators aren't supported. Dimensions are also limited to LINKED_ACCOUNT
, REGION
, or RIGHTSIZING_TYPE
.
For the GetReservationPurchaseRecommendation
action, only NOT is supported. AND and OR aren't supported. Dimensions are limited to LINKED_ACCOUNT
.
Return results that match either Dimension
object.
