Hi,
My name is James. I worked with Atlassian products in a company that was fairly tight on the administration of Jira and workflows. They had a corporate SSO running on Windows that they integrated with. Confluence and Bamboo also. I have deployed Jira, Confluence and Bitbucket with quickstarts to AWS and used Atlassian cloud. I've evaluated scriptrunner and begun learning groovy.
IAC to manage Jira and Bitbucket configurations is an area of interest.
