<div dir="ltr"><div>Thenk you all. My main concern was that master master replication is something that is used for a dual redundant deployment . Just not sure if it is reliable with multiple boxes .

<p dir="ltr">I don't know very well Postgres but I achieved pretty much the same (horizontal scaling) with a MySQL cluster. Replication is a bit painful to setup and to maintain (especially master master, including db desynchronization when crashes occur and so on). I would go for a cluster, almost endlessly scalable and very very reliable. It is more costly to setup but I think it is worth the pain.</p>
