Elixir release and deploy utilities discusses various tools for building and deploying Elixir releases, including Relx, Distillery, exrm, Heroku, Nanobox, Gatling, exdm, edeliver, dicon, Bottler, and Ansible. Distillery is highlighted as the preferred current option, as it is written in Elixir, supports umbrella apps, and is faster than the deprecated exrm. Heroku and Nanobox are noted as popular deployment targets that integrate well with Elixir apps through git pushes, while tools like edeliver and exdm focus on automating deployments including hot code upgrades.
