deployment-sca03 was there to host ores in beta cluster but with T184282: Move beta cluster ORES to its own machine I undeployed ORES from that node and we can probably just delete the instance but there are 1- Eventstream service puppet role enabled and deployment files are there 2- Recommendation API has files in /srv/deployment/.
So I don't feel comfortable deleting the instance without making sure this won't break anyone's workflow.
