Hazard analysis and Chaos engineering at Vanguard Group

Anticipating events that can cause a disruption to your system’s service is critical to building highly available, reliable systems. Hazard analysis gives you a method to identify such events.

Vanguard engineering teams perform hazard analysis on their systems and capture the identified events as failure scenarios.

To perform an FMEA more quickly, teams instead focus on the failure modes and system impact only, documenting a mental model of system performance which can be experimented through chaos engineering.

By using FMEA to anticipate the failures and experimenting on your systems with chaos engineering, you will gain confidence in the reliability of your system.
