Chaos Engineering image
  • Marie Cruz's profile
Chaos engineering is the practice of deliberately introducing failures to your system to understand how your system responds to different failures that can manifest to your users. For example, you may want to take down a random API or data service and see the side effect on your users’ applications. If the side effects are impactful and if you have Service Level Agreements (SLA) in place, then this can have a detrimental impact on your organisation.
