OPS06-BP04 Test using limited deployments
Test with limited deployments alongside existing systems to confirm desired outcomes prior to full scale deployment. For example, use deployment canary testing or one-box deployments.
Common anti-patterns:
-
You deploy an unsuccessful change to all of production all at once. You don't know.
Benefits of establishing this best practice: By testing and validating changes following limited deployment you are able to identify issues early with minimal impact on your customers providing an opportunity to further mitigate the impact on your customers.
Level of risk exposed if this best practice is not established: Medium
