First Steps with AWS Lambda, Zappa, Flask and Python 3

Update: After receiving some feedback, that it is not obvious if you need to use Python 2 or 3 for this article, I decided, that I want to update it all the way for Python 3. AWS Lambda supports it, Zappa supports it and we all want Python 3!

I wanted to try out AWS Lambda for a while now. But it took some time to find a reasonable development task that fits this infrastructure. Serverless deployment is very intriguing, escpecially for someone like me that doesn’t enjoy to fiddle with servers, operating systems and stuff.

No, I won’t reveal any detals about my project yet. But I want to share my experiences building a simple webapp – the good old hello world example – and deploy it on AWS Lambda.
