This document summarizes an webinar about EDB Failover Manager (EFM) for PostgreSQL high availability. EFM enables building highly available PostgreSQL clusters and seamlessly handles failover. It discusses key components like master and standby nodes, agents, and the witness node. The webinar demonstrates configuring, monitoring, and automating failover of a PostgreSQL cluster with EFM. It also covers failure scenarios and how EFM detects failures and performs failover in the background.

4. Webinar Covers
• Why EDB EFM
• How EDB EFM enables to build highly available PostgreSQL cluster
• What are key components and typical enterprise deployment
scenarios for EDB EFM
• Demo - How to deploy configure EDB Failover Manager

5. Open Source Database a Game Changing Trend
Cloud and open source databases are growing even faster than the
industry average.
PostgreSQL a strong Alternative to the traditional commercial
Databases
Capability to innovate rapidly to deliver new functionality, greater agility
and reduce overall TCO.
EDB PostgreSQL - an Enterprise Database Alternative to Oracle
Containment - New workloads - Migration
Revisiting previous webinar highlights

6. Moving beyond Just HA to
cluster management tool for Postgres
With main focus on the security and safety of the cluster

7. Extending the capabilities to High Availability
for Postgres in Containers
EFM helps as a controller to monitor and manage the cluster

9. Let’s deep dive into EDB EFM
Providing PostgreSQL High Availability with Automated Failover

10. • EFM
- Architecture
• EFM Supported Failure Scenarios
• Customer Setup
• Demo on configuration| Switch over & switch back |
Monitoring PostgreSQL service to detect failures automatically
We will cover:

11. EFM - EDB Failover Manager
• Master Node
• Standby Node can be 1 or more
• Witness Node
• Agents
o Runs on each nodes
o Monitor the health of Master and Standby nodes
o Talk with each other and witness to check health
of cluster
o Send notifications to DBA
o Perform Failover
• JGroups

12. EFM - Supported Failure Scenarios
• Master Database is Down
• Standby Database is Down
• Witness is Down
• Master Agent or Node Fails
• Standby Agent or Node Fails
• Nodes Become Isolated from the Cluster

13. EFM - What happens at background?
• When master database is down

14. EFM - What happens at background?
• When standby Database is down

15. EFM - What happens at background?
• When witness is down

16. EFM - Asynchronous Replication

17. EFM - Synchronous Replication
