iOS backend server for background jobs to do calculations on the data from users?

I am using Parse already for some other apps. And I have an app in mind where i would need to get data from users and periodically run a background job (scheduled) on a backend server to do some manipulations to this data. in general some simple calculations.

I was looking through Parse's documentation and it does feel a bit complicated to what I actually need. Though maybe I did' dig enough in the "cloud code" and jobs.

In my mind - if I had a server with Oracle\MySql where users send the data from the app - I can have a python script for example running every 5 minutes to do all the calculations needed...

Does anyone have an example of which platform to use for such tasks?
