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. 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! 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.
Features
- With Zappa you only pay for the milliseconds of server time that you use
- It's great for deploying serverless microservices with frameworks like Flask and Bottle
- Zappa also lets you build hybrid event-driven applications that can scale to trillions of events a year with no additional effort
- Zappa is super easy to use
- You can deploy your application with a single command out of the box!
- There's no need to worry about load balancing or keeping servers online ever again
