Python Microservices Development

Twisted and Tornado

If you are building microservices where increasing the number of concurrent requests you can hold is important, it's tempting to drop the WSGI standard, and just use an asynchronous framework like Tornado (http://www.tornadoweb.org/) or Twisted (https://twistedmatrix.com/trac/).

Twisted has been around for ages. To implement the same microservices, you need to write a slightly more verbose code like this:

    import time      import json    from twisted.web import server, resource     from twisted.internet import reactor, endpoints      class Simple(resource.Resource):         isLeaf = True         def render_GET(self, request):             request.responseHeaders.addRawHeader(b"content-type",                                                  b"application/json")  return bytes(json.dumps({'time': time.time()}), ...
