During the last years we in Aerokube team created and demonstrated truly efficient Selenium tools: Selenoid and Ggr. With two small daemons you can easily organize a reliable Selenium cluster where each browser will be running in separate Docker container.

In this talk I would like to address another important question - Selenium cluster resources consumption. I will explain step by step why running browsers in Kubernetes cluster can dramatically decrease your Selenium cluster cost. You will see how to consume times less computing resources and still have the same powerful Selenium features like video recording, debugging running tests, creating browser sessions for manual testing and so on.

I will show how to install, manage and scale Selenium cluster in Kubernetes using Aerokube Moon solution and compare resulting cluster cost to other popular solutions.
