Скачать или смотреть Automating experiments with Kotlin DSL by Aleksandr Tarasov

The big project makes simple things harder. You can not make the feature available to all clients immediately after deploy. We use experiments (or maybe you heard about feature toggle) to control step-by-step launching process. And not all of them could be successfully ended because we could have learned that the feature should be reworked or fixed by technical or product reasons.

The typical experiment has several stages each requires some amount of manual labor. It leads to waste of time and sometimes to misconfiguration. For eliminating these concerns, we have decided to automate planning and launching of experiments.

Int this talk author explains: - why Kotlin was chosen, and why classic automation tools as Ansible was not - why good, short and expressive DSL is crucial - what kind of problems we faced and how to solve them all to make it worked as intended initially
