Over the years, Atlassian has worked very hard to tie their products together. The result has been a smooth user experience across systems. Users can work in the system they are currently in, and switch to others via application links.
Confluence and JIRA interact with one another very closely. In one of our live webinars, my colleague, Jan Kuntscher, and I demonstrate JIRA integration in Confluence.

Here's a video of the session:
