Differencs between Single-Site and multiple site in cloud

[tetralog systems AG]

Hello,

we are currently running Jira and confluence on our own premises and will migrate both to cloud soon. Before doing so, there is the decision to make whether we want to have both on one site in the cloud or have multiple sites, one for each application. 

Neither the support at atlassian nor the interwebs could show me what the main difference between the two models is. 

If i have both applications on one site, will ther be some kind of "landing page" where i select if i want to open jira or confluence? do they both have different subdomain names? 

I would like to get an understanding what this would in the end look like for the everyday user. Can someone enlighten me and help me choose what approach i should take?

Thanks and best

You could query the Confluence database. Here is an article from 2010 but the concepts are sound:
