Enterprise architecture system and method
A method for costing a web service operable for querying one or more data sources, the method including calculating the cost of operating the web service, measuring web service usage data using one or more service metrics, wherein the one or more service metrics include at least one derived service metric, choosing at least one service metric from the one or more service metrics, wherein one or more of the at least one chosen service metrics is a derived service metric, calculating the cost of the web service based on the at least one chosen service metric, and charging for usage of the web service based upon the calculated cost of the web service.
1. A method for costing a REST web service operable for querying one or more data sources, the method comprising:
calculating the cost of operating the web service;
measuring web service usage data using one or more service metrics, wherein the one or more service metrics include at least one derived service metric;
choosing at least one service metric from the one or more service metrics, wherein one or more of the at least one chosen service metrics is a derived service metric;
calculating the cost of the web service based on the at least one chosen service metric; and
charging for usage of the web service based upon the calculated cost of the web service.
2. The method of claim 1 , wherein the at least one derived service metric comprises custom data related to the REST web service generated by the REST web service in response to the querying one or more data sources.
3. The method of claim 2 , wherein the at least one derived service metric comprises one or more of the set including: a response identifier, a query, a list of one or more data providers, a transport protocol, an indication of whether a proxy is used, a request identifier, a request time stamp, a response time stamp, an indication of whether the request was served from unexpired cache, an indication of whether the response was used to populate a response cache, size of the response, or throughput.
4. The method of claim 1 , wherein the at least one derived service metric comprises custom data related to the REST web service and the one or more data sources generated by the REST web service in response to the querying one or more data sources.
5. The method of claim 4 , wherein the at least one derived service metric comprises one or more of the set including: a response identifier, a namespace of the queried data source, an indication of whether an operating level agreement has been satisfied, a request time stamp, a response time stamp, a requester identifier, content length, or throughput.
6. The method of claim 1 , wherein calculating the cost of the web service based on the at least one chosen service metric comprises dividing the cost of operating the web service by the at least one chosen service metric.
7. The method of claim 6 , wherein calculating the cost of operating the web service comprises the steps of:
determining a cost to the REST web service for all requests to each of the one or more data sources for which web service usage data was measured;
determining an operating cost of the REST web service for all requests to the REST web service for which web service usage data was measured; and
determining a total cost for all requests to the REST web service by summing the cost to the REST web service for all requests to each of the one or more data sources and the operating cost the REST web service.
8. The method of claim 7 wherein charging for usage of the web service based upon the calculated cost of the web service further comprises summing the cost of the web service with a flat fee.
