Deis 是一个 Django/Celery API 服务器、Python CLI 和一组 Chef cookbooks 合并起来提供一个类似 Heroku 的应用平台，用于公有云和私有云。Deis 的口号是：Your PaaS. Your Rules.
Deis 是一个开源的 PaaS 系统，简化和 LXC 容器和 Chef 节点的发布和伸缩。可用于托管应用、数据库、中间件和其他服务。Deis 利用 Chef、Docker 和 Heroku Buildpacks 来提供的私有 PaaS 是非常轻量级和灵活的。
Deis 提供开箱即用的 Ruby, Python, Node.js, Java, Clojure, Scala, Play, PHP, Perl, Dart 和 Go 语言的支持。此外 Deis 可使用 Heroku Buildpacks、Docker images 和 Chef recipes 发布任何内容。Deis 主要设计用来跟不同的云提供商进行交互，尽管目前只支持 EC2。
