1. A computer system comprising: a processor; and a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to: generate service instances of computing systems according to associated configuration parameter sets and respective corresponding configuration parameter values, determine configuration parameter value changes in the configuration parameter sets for each generated service instance of the computing systems, compare the configuration parameter value changes for each generated service instance with a first subset configuration parameter values and with a second subset configuration parameter values, and propagate the determined configuration parameter value changes in one service instance to another service instance according to a definition of rules for mapping configuration parameters and their values between second subsets of configuration parameters.
