Doubt on topology with load balancing

Is there any way to create a load balance so that the database is unique for all clients?

I would not like to have several astpps each with a data bank to provide maintenance, this is, in this load balancing, regardless of which astpp to the link is addressed, or data bank is used or the same.

I don’t see any difficulty in the balance questão, but at least I have to do how to do it in relation to the craps bank. Do we have a light? I only seek advice from practical boas.

@Francisco I am not getting your concern.Are you talking about mysql proxy ?
Like for every clients unique database , how exactly you are planning ?
