This workshop shows how to build efficient and scalable browser automation infrastructure using new tools: Selenoid and Ggr. You will be taught why running browsers in containers is so efficient, how to easily install Selenoid for local development and then create a fault-tolerant cluster with Ggr load-balancer.

To attend this class it is recommended to have some experience with Selenium, Linux shell and Docker. We also expect to have Docker installed on your computer and have some example Selenium tests to run.
