Detecting impedance mismatches due to cross-service calls

摘要

Systems and methods are described for conducting static analysis of code invoking network-based services to identify, without requiring execution of the code, an impedance mismatch between an expected execution rate of the code and an invocation capacity of a service invoked within the code. A system is provided that may analyze code to detect both direct invocations of services, as well as indirect invocations caused by the direct invocations. The system can utilize information regarding directly or indirectly invoked services to determine whether an expected invocation rate of such services will exceed invocation capacity for the services. In some instances, the system can traverse a “call graph” of all services invoked by code either directly or indirectly to identify impedance mismatches through multiple levels of indirection.
