PostgreSQL High Availability (HA) is a very desirable goal for most, if not a strict requirement. And there are technologies and literature to help provide HA on a PostgreSQL cluster.

However at Groupon we manage hundreds of database servers, distributed across several datacenters in the world. And our internal policy mandates that we need a Disaster Recovery mechanism to switch a complete datacenter over to another.

With this main requirement we have built Hydra, a soon-to-be-open-sourced solution that implements geo-redundant failover. It relies on Consul for distributed consistency and as the basis for the multi-datacenter approach, and is implemented as a lightweight agent in Java8.
