Abstract
A system includes: at least one processor running instances of two or more services. Instances of a first service are dependent upon instances of a second service. A fault-injection manager, based on data in a service directory indicative of dependencies of services of the system, determines a fault-inducing condition to inject into the system and injects the fault-inducing condition into the system. A health monitoring manager detects failures in the system and identifies the first service as vulnerable to the fault-inducing condition when the fault-inducing condition causes an instance of the second service to fail.
