Method and system for building and managing dynamic rate cards for use with cloud service subscriptions

A system, comprising:

• one or more computers comprising one or more microprocessors;
• a cloud environment running on the one or more computers;
• a plurality of services deployed within one or more realms of the cloud environment;
• and
• a rate card service operable in a realm of the cloud environment controlled by a cloud infrastructure provider, the rate card service being operable to:
• identify a plurality of usage rates corresponding respectively to a plurality of cloud computing services, wherein values for the plurality of usage rates are modifiable over time;
• generate a first set of rate cards that respectively indicate a first set of values for a corresponding first set of usage rates of the plurality of usage rates;
• store the first set of rate cards in a mutable data structure, wherein the mutable data structure is modified responsive to determining that a change has occurred in a value of at least one of the first set of usage rates;
• generate a second set of rates cards that respectively indicate a second set of values for a corresponding second set of usage rates of the plurality of usage rates;
• store the second set of rate cards in a semi-immutable data structure, wherein the semi-immutable data structure is not modified responsive to determining that a change has occurred in a value of any of the second set of usage rates;
• store an association between the mutable data structure and a first plurality of affiliations in a first one-to-many relationship;
• store an association between the semi-immutable data structure and a second plurality of affiliations in a second one-to-many relationship;
• execute a first memory read operation to obtain a first usage rate value in the mutable data structure to determine a respective first set of applicable values for service usage, corresponding to a first rate card in the first set of rate cards, by two or more of the first plurality of affiliations of the plurality of cloud computing services;
• and
• execute a second memory read operation to obtain a second usage rate value in the semi-immutable data structure to determine a respective second set of applicable values for service usage, corresponding to a second rate card in the second set of rate cards, by two or more of the second plurality of affiliations of the plurality of cloud computing services.

One or more non-transitory computer readable storage media storing program instructions that, when executed by one or more hardware processors, cause performance of operations comprising:

• identifying a plurality of usage rates corresponding respectively to a plurality of cloud computing services, wherein values for the plurality of usage rates are modifiable over time;
• generating a first set of rate cards that respectively indicate a first set of values for a corresponding first set of usage rates of the plurality of usage rates;
• storing the first set of rate cards in a mutable data structure, wherein the mutable data structure is modified responsive to determining that a change has occurred in a value of at least one of the first set of usage rates;
• generating a second set of rates cards that respectively indicate a second set of values for a corresponding second set of usage rates of the plurality of usage rates;
• storing the second set of rate cards in a semi-immutable data structure, wherein the semi-immutable data structure is not modified responsive to determining that a change has occurred in a value of any of the second set of usage rates;
• storing an association between the mutable data structure and a first plurality of affiliations in a first one-to-many relationship;
• storing an association between the semi-immutable data structure and a second plurality of affiliations in a second one-to-many relationship;
• executing a first memory read operation to obtain a first usage rate value in the mutable data structure to determine a respective first set of applicable values for service usage, corresponding to a first rate card in the first set of rate cards, by two or more of the first plurality of affiliations of the plurality of cloud computing services;
• and
• executing a second memory read operation to obtain a second usage rate value in the semi-immutable data structure to determine a respective second set of applicable values for service usage, corresponding to a second rate card in the second set of rate cards, by two or more of the second plurality of affiliations of the plurality of cloud computing services.
