I am looking into options to export data to ftp, such as stock feed and pricing, so customers can access this data for their webshops. I don't have much programming knowledge, but came across a few options such as ETL and a crone job to export this data. 

I assu e there should be some best practices for this, both in terms of reliability, easy of maintenance (ie when upgrading the system).

I am considering a midleware option that extracts data and then posts it. If we decide to upgrade or switch to even other erp, the transition should be easier I assume. Also, further scaling such other data can be easily extracted and posted some other place is important. 

Anyway, if you have insights in this and can explain it to someone with litle (close to nothing) understanding of Python and other code, would be greatly appreciated.
