Hi all! I need help finding a more robust solution for service mapping, related to "guardrail" CI´s on my CMDB. There are hundreds of thousands of CI´s created on our AWS instance that we already discover and have a set of key value tags. So depending on those tag values, i would like to automatically map it to an application service. I know this is already possible via the CSDM > Manage Technology Management Services > Service Instance, however it is limited and i need a robust and automatic solution due to the amount of CI´s. I could create a script but would like to know what would be the corret way to do it. thanks in advance!

@Daniel Braga  The Tag-based service mapping would take care of it, irrespective of the number of CI's. you can try doing it. What exactly is "guardrall"? In the "cmdb_key_value" table, what is the key which has 'guardrall' as the value. 

I did the step by step guidance for tag-based service mapping for one of the requesters in Community. Here is the link: Go through it and do let me know if you still have questions OR struck at some point.
