Many people started using ClearDB MySQL database on Windows Azure before it was offered through Windows Azure Store which enables easy management of the service. You can still manage those but you need to do few steps before you are able to do that.
- Go to Windows Azure dashboard portal
- Open your website
- Click "View Connection Strings" and take up Database, User Id and Password
- Go to ClearDB upgrade website and fill in the details that you collected before
- Now you can create your ClearDB account and have your MySQL database connected into it.
