Run script on remote server from Django Webserver

I have a basic (server1) Django development web server and another server (server2) which has a python script that does some scientific calculations. Assume that the server1 has necessary authentication in place to run the script on server2. All I want to do is, click a button on the django website which would run the python script sitting on server2.

Ideas that I have so far are,

Not sure if above ideas would work, please suggest your insight into this and if possible a simple example would be appreciated.

More info: Server1 and Server2 has to be 2 separate servers, server1 is a webserver, while server2 can be any linux virtual machine. Also, the response from server2 has to be sent back to server1.

After reading through and trying out various forum suggestions and spending solid time in Google, I've settled down with paramiko. It does exactly what I wanted and works like a charm for now.

On click of a button on my website, running on server1, I make a request to run a python script. The python script uses paramiko to make SSH connections to server2, runs the necessary command and writes a response to a plain/text file. This plain/text file is rendered back to the request through django form as a response.

This looks a little dirty now and there are more things to look into like, what happens if the command took very long time to execute or it erred out for some reason. I haven't spent time in figuring out answers for all those questions, but eventually will.

There is no reason why server one cannot execute something like selenium or phantomjs on itself to navigate to your website on server2 and click a button on server 2 which then uses something like python's subprocess module to execute a program from server 2.
