Deis vs. Engine Yard Cloud vs. Modulus

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.

The Engine Yard Platform as a Service (PaaS) is a product family that leverages open source technologies to orchestrate and automate the configuration, deployment and management of applications on multiple infrastructures.

Modulus is a premier Node.js hosting platform that provides a complete technology stack for application developers. This includes custom SSL, WebSockets, MongoDB, statistics, and more.
