[Pdns-users] Multi server deployment

Hi all,
we are looking to migrate from bind to PowerDNS with MySQL backend. Our initial tests have gone really well and we are now looking into finalizing the architecture for the final deployment and migration. In that respect we have a couple of doubts.

Since we are going to be using the MySQL backend, and we are going to have multiple PowerDNS servers deployed, is it possible to have several instances of pdns share the same backend? How does that affect slave updates in case a master has more than one slave configured and both slaves use the same backend?

If its not possible to use the same backend, we are thinking of using MySQL replication, master-slave, and have only one pdns instance listed as slave. What we don't like about this setup is the lack of redundancy since in order to have more than one slave listed we would have to use master-master replication, which we are trying to avoid.

What are your thoughts on this? Are there any best practices/recommendations for large deployments? Thanks in advance for all your help.
