I searched for answer to this question, but didn't come across a topic that seems to have directly addressed it. Hence I am posting it as a new question.
From this Google App Engine page, it says that webapp2 is a lightweight framework that allows you build simple web applications for the Python 2.7 runtime.
The emphasis above seems to be on simple web applications. Given this I wonder if it hints at webapp2 python framework not being suitable for large scale complex applications that need to scale to several million users. What is the reason that it wouldn't scale (because I thought Google App Engine is a platform designed to scale regardless of what language or framework one uses).
I am trying to make a decision of whether to use the webapp2 python framework (easier to learn and get going) for my website that might potentially have to scale to the millions of users or if I should consider other frameworks.
