Yes, the idea is to create a VM with the database and the render, then upload the files to regular Apache server I already got on a shared host. Therefore, it'd be no problem if it becomes slow, after the rendering this wouldn't make difference, since the VM wouldn't be exposed as a server to the internet.
The wiki page mentions the import of planet.osm. Since I'm going to work with other data, can I just create a sketch on JOSM them import it or should I use anything else like the planet boundary? I really need only Rio de Janeiro's downtown bbox, so anything else would be a waste of database space/rendering time. Thanks a lot!
