Envoyer vs. Engine Yard Cloud vs. Stackato

Envoyer deploys your PHP applications with zero downtime. Just push your code, and let Envoyer deliver your application to one or many servers without interrupting a single customer. In this series, we'll discuss each feature of Envoyer, demonstrating how to use them with a sample project.

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.

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.
