Zappa isn't just for WSGI, you can also build massively parallel event driven applications with async task invocation!

Read the project’s introduction
Project moved to https://github.com/zappa/Zappa. Versions after 0.52.0 are published from there. Thank you Rich Jones for all your work on creating Zappa and maintaining it for years!

16 sourcesI've been using Zappa https://github.com/Miserlou/Zappa for a few side projects and even at work, and you can definitely set up a robust version-controlled, CI + UAT + CD pipeline if you have the discipline.
* Dev: develop inside Docker container identical to Lambda environment https://github.com/lambci/docker-lambda
* CI: test via Jenkins/GoCD/Travis/CircleCI, inside docker
* Staging: deploy to staging host on merge
* UAT: against staging env, break build if any user-facing tests fail
* Prod: deploy exact same package we deployed to Staging

> The Lambda free tier includes 1M free requests per month and 400,000 GB-seconds of compute time per month.
> The Lambda free tier does not automatically expire at the end of your 12 month AWS Free Tier term, but is available to both existing and new AWS customers indefinitely.
(emphasis added)
That is awesome. Providing you could get your application compatible with lambda. This application may help for WSGI-based (python) applications: https://github.com/Miserlou/Zappa

In Ask HN: What free services can I use for a back-end?Serverless / Zappa, hosting my API’s for 10x decrease in monthly costs.
https://github.com/Miserlou/Zappa
In Ask HN: How did you significantly reduce your AWS cost?This is true of any project using Zappa, right? https://github.com/Miserlou/Zappa
The python project defines a wsgi application (which is a python function meeting the wsgi spec), and Zappa runs the function on Lambda.
I wonder how large Zappa sites have gotten.
In Serverless dev practices questionsI'd recommend using a framework such as the Serverless Framework[1], Chalice[2], Dawson[3], or Zappa[4]. As any other (web) development project, using a framework will alleviate a big part of the pain involved with a new technology.
Anyways, I'd recommend starting from learning the tools without using a framework first. You can find two coding sessions I published on Youtube[5][6].

In Ask HN: How was your experience with AWS Lambda in production?I used Zappa[0] and AWS Lambda to host a Flask application recently. After years of deploying Flask applications to VPSs behind Apache, I was pretty impressed by how simple it was to deploy a serverless app. Nice that there's no need to worry about security patches, OS updates, HTTPS cert renewals, etc. And so far it's waay cheaper for my usage too. If your Django app doesn't have too many dependencies, it might be worth considering. Then you can use AWS Simple Email Service (or any of the many third-party services already recommended) for the email needs.

In Support for tagging of Lambda functions and for the Python 3.6 runtimeYep!
Follow the progress here: https://github.com/Miserlou/Zappa/issues/793
In Support for tagging of Lambda functions and for the Python 3.6 runtimeFinally Zappa(https://github.com/Miserlou/Zappa) would be able to support web services written in python 3!
In Support for tagging of Lambda functions and for the Python 3.6 runtimeWe've had a lot of success deploying python web apps with Zappa: https://github.com/Miserlou/Zappa
The value is that it does deploy, the route-mapping, config management, and also allows you to 'keep-warm' if you want to keep the backend responsive even after zero/low traffic.
My hope is that best practices are going to continue being distilled into these deployment/wrapper frameworks.
In AWS Lambda – Best practicesServerless[0] does support Python (the CLI tools are just written in JS). Zappa[1] is also a great option if you want to deploy a WSGI compatible app (flask/django) to Lambda.
I've used them both in production and have had a great experience.

In Have Your MVP Running Publicly Within 15 Minutes with ServerlessI've been using and loving Zappa[1] lately. Basically it lets you seamlessly deploy a flask app to AWS Lambda -- that solves your deployment, scaling, upgrading, staging, backups, etc. And local dev is just running the flask app locally.
