We made GitLab Runner Autoscale https://gitlab.com/gitlab-org/gitlab-ci-multi-runner/issues/... that can automatically spin up more droplets via Docker Machine to run your CI tests. We use it ourselves for GitLab builds (up to 100 machines) and enabled it for all GitLab.com users. For more information see the announcement https://about.gitlab.com/2016/03/29/gitlab-runner-1-1-releas... Feel free to ask questions.
