Abstract
Techniques for evaluating a second version of software. Embodiments selectively route incoming requests to software instances within a plurality of baseline instances and a plurality of canary instances, where the baseline instances run a first software version and the canary instances run the second software version. The software instances are monitored to collect performance data for a plurality of performance metrics. Embodiments calculate aggregate baseline performance metrics, where each of the aggregate baseline performance metrics is calculated based on the collected performance data for the plurality of baseline instances. For each of the performance metrics and canary instances, embodiments calculate a relative performance value that measures the collected performance data for the respective canary instance and for the respective performance metric, relative to the corresponding aggregate baseline performance metric. A final measure of performance is calculated for the second version of software, based on the relative performance values.
