Kayenta is an open-source automated canary analysis service developed by Netflix and released under the Apache 2.0 license. It is designed to facilitate the continuous delivery process by enabling users to identify problems in new software releases early through statistical analysis of key metrics. By running parallel comparisons between baseline and new service instances (known as canaries), Kayenta assesses the performance and reliability of new deployments in real-time. It integrates with various data sources and cloud platforms, allowing teams to enhance their deployment strategies with actionable insights and data-driven decisions.
