Presented in Moscow in December 2017 at the Heisenbug conference. Video and slides are in Russian.
# Abstract
Every day the systems we develop become more and more complicated. It seems there is nowhere to hide from the ubiquitous complexity. One of its aspects is configuration. On the one hand, configuration has a significant influence on the stability and availability of a system. On the other hand, there is too little time set aside for checking its correctness. In this talk, we’ll explain how we test configuration and how useful it has been for our project.
This talk will be helpful for those who want to learn an easy way to increase system stability and availability in production.
