Abstract: A fault injection system for a cloud infrastructure utilizes fault injection agents instantiated on components of the cloud infrastructure to inject fault into the components. The faults are based on fault definitions which define the type(s) of fault(s) to inject, the scope for injecting the fault into the cloud infrastructure, deployment information for deploying the fault in the cloud, and remediation information which defines a plan for remediating the fault in the cloud infrastructure. The system monitors the impact of faults on the components which enables component dependencies to be determined.
