Still another analytic generated by analyzer 114 anticipates affects related to proposed microservice changes. The analytic is derived from constructor 112 constructing one or more new or revised invocation matrices based on proposed newly added or dropped interfaces between one or more microservices. The newly constructed or revised invocation matrices can be used to generate a corresponding new or revised network matrix. Analyzer 114 can perform matrix subtraction by subtracting the network matrix corresponding to a current version of the network from a network matrix corresponding to the proposed version. The resulting matrix indicates the specific interfaces and corresponding microservices most likely to be affected by the proposed changes.
