Sharing MySQL servers with other instances
Your MySQL server, as well as other services can be accessed from another instance attached to your private network.
When you first launch an instance, you have the option to "share" the instance with another instance you own. The effect of this is the newly created instance is attached to the network of the instance you choose to share with.
