Hi there,
well I am still discovering Jira+Confluence ecosystem. Surprisingly, our project is a cloud development, and we chose Jira & Confluence server distributions ... hosted on the cloud!
Cheers
I liked the cloud version better, had a more cool features, as did Confluence.
They are great tools as you can easily link tickets in Confluence pages and they auto-update. This allows non-JIRA users ability to view Confluence pages and ticket status.
Enjoy!
