With use of modern deployment tools like Ansible, a high availability stack is built with only open-source products. Automatic fail-over, Backup- recovery, Monitoring, SSL, Virtual IP and an environment to manage the stack is part of the setup. Complete setup with industry-standard tools like Barman, Repmgr, Prometheus/Grafana, HAProxy and Keepalived. This talk will deliver a live demo of building the environment, and testing a demo application while doing a switch over, and prove that no transactions are lost.
