How to connect to my new mysql DB on the cloud?

I'm trying to figure out the whole idea of databases in a cloud environment, or more correctly - data management on the cloud. I've recently created a test database on what is called a mysql cloud env. and I'm trying to connect开发者_JAVA百科 to it - anyone have any experience with this? I get connection errors. After that, I'm wondering what is the best way to populate the database with the data from my old MySQL. Any tips are welcome! Thanks :)

Regarding connection errors: what errors?

On how to move data:

• export data (use mysqldump)
• upload to server (ftp?)
• import (use mysql command line)
