Google App Engine vs octohost: What are the differences?

Google App Engine: 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; octohost: Simple web focused Dockerfile based PaaS server. octohost helps you host any web site by adding a Dockerfile to your app's source repository.

Google App Engine and octohost can be primarily classified as "Platform as a Service" tools.

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.
