Google App Engine vs Stackato: What are the differences?

Developers describe Google App Engine as "Build web applications on the same scalable systems that power Google applications". Google has a reputation for highly reliable, high performance infrastructure. With App Engine you can take advantage of the 10 years of knowledge Google has in running massively scalable, performance driven systems. App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs grow. 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.

Google App Engine and Stackato belong to "Platform as a Service" category of the tech stack.

Some of the features offered by Google App Engine are:

• Zero to sixty: Scale your app automatically without worrying about managing machines.
• Supercharged APIs: Supercharge your app with services such as Task Queue, XMPP, and Cloud SQL, all powered by the same infrastructure that powers the Google services you use every day.
• You're in control: Manage your application with a simple, web-based dashboard allowing you to customize your app's performance.

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

• Web console
