Deis vs Stackato: What are the differences?

Developers describe Deis as "Open Source PaaS that builds upon Docker and CoreOS to provide a lightweight PaaS with a Heroku-inspired workflow". Deis can deploy any application or service that can run inside a Docker container. In order to be scaled horizontally, applications must follow Heroku's 12-factor methodology and store state in external backing services. On the other hand, Stackato is detailed as "Enterprise ready private PaaS based on the Cloud Foundry open-source project and Docker". Stackato runs on top of your cloud infrastructure, and is the middleware from which your applications are launched. Developers simply upload their application source files to Stackato via IDE or command-line. Stackato automatically configures the required language runtimes, web frameworks, and data and messaging services.

Deis and Stackato can be primarily classified as "Platform as a Service" tools.

Some of the features offered by Deis are:

• Deis can deploy any language or framework using a Dockerfile
• If you don't have a Dockerfile, Deis includes Heroku buildpacks for Ruby, Python, Node.js, Java, Clojure, Scala, Play, PHP, Perl, Dart and Go.
• Deis can be deployed on any system that supports CoreOS including your workstation, as well as most public clouds, private clouds and bare metal.

On the other hand, Stackato provides the following key features:

• Web console
• Activity timeline
• Multi-tenancy
