Fault Injection
A Survey on Failure Analysis and Fault Injection in AI Systems
This study presents a detailed survey of existing FA and FI approaches across six layers of AI systems. We systematically analyze 160 papers and repositories to answer three research questions including (1) what are the prevalent failures in AI systems, (2) what types of faults can current FI tools simulate, (3) what gaps exist between the simulated faults and real-world failures.

MicroFI: Non-Intrusive and Prioritized Request-Level Fault Injection for Microservice Applications
This paper presents MicroFI, a non-intrusive fault injection framework, aiming to efficiently test different application functions with request-level injection. Request-level injection limits the blast radius to specified requests without any source code modification.

A Framework of Virtual War Room and Matrix Sketch-Based Streaming Anomaly Detection for Microservice Systems
In this paper, we build a system named “VWR”, a framework of Virtual War Room for operating microservice applications which allows users to simulate their microservice architectures with low overhead and inject multiple types of faults into the microservice system with chaos engineering.
