Think of it as "serverless" web hosting for your Python apps. That means **infinite scaling**, **zero downtime**, **zero maintenance** - and at a fraction of the cost of your current deployments! If you've got a Python web app (including Django and Flask apps), it's as easy as: ``` $ pip install zappa $ zappa init $ zappa deploy ``` and now you're server-less! _Wow!_ > What do you mean "serverless"? Okay, so there still is a server - but it only has a _40 millisecond_ life cycle! Serverless in this case means **"without any permanent infrastructure."** With a traditional HTTP server, the server is online 24/7, processing requests one by one as they come in. If the queue of incoming requests grows too large, some requests will time out. With Zappa, **each request is given its own virtual HTTP "server"** by Amazon API Gateway. AWS handles the horizontal scaling automatically, so no requests ever time out. Each request then calls your application from a memory cache in AWS Lambda and returns the response via Python's WSGI interface. After your app returns, the "server" dies. Better still, with Zappa you only pay for the milliseconds of server time that you use, so it's many **orders of magnitude cheaper** than VPS/PaaS hosts like Linode or Heroku - and in most cases, it's completely free. Plus, there's no need to worry about load balancing or keeping servers online ever again. It's great for deploying serverless microservices with frameworks like Flask and Bottle, and for hosting larger web apps and CMSes with Django. Or, you can use any WSGI-compatible app you like! You **probably don't need to change your existing applications** to use it, and you're not locked into using it. Zappa also lets you build hybrid event-driven applications that can scale to **trillions of events** a year with **no additional effort** on your part! You also get **free SSL certificates**, **global app deployment**, **API access management**, **automatic security policy generation**, **precompiled C-extensions**, **auto keep-warms**, **oversized Lambda packages**, and **many other exclusive features**! And finally, Zappa is **super easy to use**. You can deploy your application with a single command out of the box! __Awesome!__ <p align="center"> <img src="http://i.imgur.com/f1PJxCQ.gif" alt="Zappa Demo Gif"/> </p> ## Installation and Con
