• The ultimate goal of a PaaS is to make it easier for you to run your website or web application no matter how much traffic it gets.

• You just deploy your application and the service figures out what to do with it.

• A platform as a service should handle scaling seamlessly for you so you can just focus on your website and the code running it.
