However, performance test execution and evaluation shouldn’t be a manual process and certainly shouldn’t be limited to dedicated testing teams. Zero-downtime deployment strategies such as blue/green or canary releases introduce built-in recovery mechanisms to reduce the impact of defects on production users.
