Chaos Engineering is the discipline of experimenting with a system with the aim of increasing confidence in its ability to withstand problems in your environment.

Testing in non-productive environments should be performed regularly and should be part of the CI/CD cycle. In production, teams must perform the tests in such a way as not to cause the service to be unavailable.

Test results should be measured and then compared with availability objectives to understand whether the application running in a particular environment is able to achieve the defined objectives.
