The Testing Farm Team has been fighting an unreliable testing infrastructure for years. Last year we got the possibility of a failover from our internal OpenStack cloud to the public cloud (AWS). In this session, we will guide you through our journey of adding a transparent failover functionality to our CI pipeline, with AWS complementing an OpenStack tenant. We will look at the requirements on the AWS cloud in terms of connecting it to the internal infrastructure and at the main features of our open-source provisioner Artemis, which made this failover possible: a programmable routing mechanism. In addition to the actual provisioning, Artemis also shields us from short-lasting infrastructure outages, which previously caused irrecoverable failures in our CI pipeline. In the end, we would like to show you how you can take advantage of Artemis for your own benefit and share the interim plans of adding support for additional public clouds, Beaker, and more features planned by the team.
