Introducing Kayenta: An open automated canary analysis tool from Google and Netflix

Speed and scalability bottlenecks: For organizations like Google and Netflix that run at scale and that want to perform comparisons many times over multiple deployments in a single day, manual canary analysis isn’t really an option.

Configuring dashboards for each canary release can be a significant manual effort, and manually comparing hundreds of different metrics across the canary and baseline is tiresome and laborious.
