Automation of IT operations from cloud

Hello,

I have a number of Linux shell scripts for automation of particular operations. For example: merging SVN revisions from one branch to other, update statuses of JIRA tickets, make an Oracle eBS build from sources stored in SVN or git etc. 

I'm trying to use these automation scripts for different infrastuctures and customers. But I cannot share the script code for mentioned customers. Is it possible to put automation shell scripts in cloud and call these scripts from different infrastuctures? Are some available technical solutions how to call Linux shell scripts from cloud?

For example in cloud I could have shell function svn_merge() with parameters. But this script could be called from different infras with different parameters like "svn_merge <parameters>".

I will be happy to see any suggestions, any links to any free or commercial solutions.

Thanks in advance!
