 We ensure that all releases are deployable as [Docker](https://www.docker.com/) containers.  While we don't regularly test other methods of deployment, our community has documented deployment strategies for AWS, [Digital Ocean](https://gist.github.com/jshimko/745ca66748846551692e24c267a56060), and Galaxy.
