Gigalixir is a platform as a service for production applications, built for Elixir and Phoenix. It offers distributed clustering, a Remote Observer, a Remote Console and SSH access, and supports both Mix and Elixir Releases. Applications are deployed through buildpacks and a Procfile, and other languages such as Ruby, Node.js, Python and Go are also supported. Managed PostgreSQL with read replicas and backups is part of the offering, and the documentation mentions hot upgrades. The service is SaaS, operated through a web console and a CLI.
Gigalixir is operated by Vesper Summit, LLC. Applications run on AWS or GCP, both US cloud providers, in regions in the United States and Europe. An organisation that wants to keep personal data inside the EU therefore needs to select a European region deliberately. The platform itself is not open source, although the CLI and the buildpacks are published as open source projects on GitHub. For a European organisation this means a commercial US provider on US infrastructure, with European regions as an option.
