Getting mirrormaker into my cloud database

At work I’ve been getting really used to working with fully developed databases.

But now that we’ve had some shifts in the company, I can no longer rely on somebody else and I need to set up my own database.
We’ve now switched to a database in the cloud and I still need some time getting used to it.

I need to send all the relevant data up to marketing, so they can have their fun with it and figure out some new target audiences and whatever. But to make it all work I can’t just take the data out.
Mirrormaker would be the perfect approach, but I can’t get it into the cloud. Now I’ve been thinking about using a third-party software to help the whole process. Do you think it could work using something like aiven ?

What are you doing with Xojo in regards to the databases?
