Salman Ahmed wants to be highly available:
We are thrilled to announce the release of pg_cirrus! First of all, you might be wondering what “cirrus” means. The term refers to the thin and wispy clouds that are often seen at high altitudes.
pg_cirrus is a simple and automated solution to deploy highly available 3-node PostgreSQL clusters with auto failover. It is built using Ansible and to perform auto failover and load balancing we are using pgpool.
Read on to see how it works. It’s also licensed under GPLv3, so it’s not only highly available but also freely available.
