Know-how of utilizing trained model for web applications

I have trained my model in keras. And I am trying to deploy this model to my web applications. In such case, how do you guys deploy this model to web applications; like interactive chat applications. I think django is suitable because my model is in python.

So what I want to know is that is there any know-how web pages or books of deploying trained model? I do not need to train online via web applications, just deployment.
