| The formula for doing so would be: | |

| The script should take input from STDIN. |

We now have everything we need to build a web app, except for images and other binary files. Your application will likely not get a lot of engagement if its not visual. In this lesson, we shall be adding the ability to upload images to your Posts api.
Since this will be a continuation from the class on Deploying to production you are adviced to start by cloning that workspace and then working from there.
In this session, we are going to mimic a posts api that we worked on in a previous class. Typecode provides the free sample api.
APIs are what enable the backend, frontend and your mobile application to work together. We have also seen how to build basic REST api using Django Rest Framework
To get the post API to work we will need to work on four modules:
For the lesson today, we are going to deploy our application to a live server.
The current workspace provided by cloud9 is meant only for development and not for production. By that, we mean you can use the service to write and even test your code but not to run your service.
For this we will be using a platform called heroku. Heroku is a PAAS (Platform As A Service).
This means you will not need to work VMs and such. Heroku will work with your code as long as you push it, which do using a similar technique.
The main things to consider when hosting your code will be:
