Heroku vs. Clever Cloud vs. Engine Yard Cloud

Heroku is a cloud application platform – a new way of building and deploying web apps. Heroku lets app developers spend 100% of their time on their application code, not managing servers, deployment, ongoing operations, or scaling.

Clever Cloud is a polyglot cloud application platform. The service helps developers to build applications with many languages and services, with auto-scaling features and a true pay-as-you-go pricing model.

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.
