PGConf.Russia 2015

The talk will describe the present state of national information technologies and DBMS, present state and future of using open source software in the defence industry.

Methodology and results of comparative testing of various databases capable to solve the problem of independence of foreign vendors, will be presented.

The Corosync/Pacemaker framework which is part of the LinuxHA stack can be used to provide monitoring and automatic failover capabilities. Now with streaming replication in place, it makes sense to use this robust infrastructure for PostgreSQL master and its replica handling. The open source pgsql resource agent also does this now. This talk will talk about using Corosync/Pacemaker with Postgres.
