![]() ![]() Each request then calls your application from a memory cache in AWS Lambda and returns the response via Python's WSGI interface. AWS handles the horizontal scaling automatically, so no requests ever time out. With Zappa, each request is given its own virtual HTTP "server" by Amazon API Gateway. If the queue of incoming requests grows too large, some requests will time out. ![]() With a traditional HTTP server, the server is online 24/7, processing requests one by one as they come in. 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." If you've got a Python web app (including Django and Flask apps), it's as easy as: $ pip install zappa That means infinite scaling, zero downtime, zero maintenance - and at a fraction of the cost of your current deployments! ![]() Think of it as "serverless" web hosting for your Python apps. Zappa makes it super easy to build and deploy server-less, event-driven Python applications (including, but not limited to, WSGI web apps) on AWS Lambda + API Gateway. In a hurry?
