Presented at PGConf US 2017
RDS is great. But sometimes you feel the need for more flexibility and customization that is just not possible with RDS. In this talk I will talk about why one might want to go with setting up and maintaining a HA postgres cluster on EC2 instead of RDS, following which I will go through each of the steps for setting up such a system and automating installation and upgrades, replication, backups and restores with S3, PITR, monitoring with Cloudwatch and failover. This talk is especially useful for people looking to gain a better understanding of how the various AWS tools can be used together for a HA postgres cluster, and as a HowTo guide on migrating from either RDS or their own hosted cluster on to EC2.
