Version FINAL

Lecture: Easy Geo-redundant Failover with MARS and systemd

Howto Survive Serious Disasters

The talk describes a simple setup of long-distance replication with minimum effort. The new systemd interface of MARS will drastically reduce your effort to make your existing complex solution geo-redundant.

Geo-redundancy / mass data replication over long distances is now much easier to manage for sysadmins. Although systemd has some shortcomings and earns some criticism, it can ease your automation of handover / failover when combined with the new unit-file template generator from the long-distance data replication component MARS. It is very flexible, supporting arbitrary application stacks, virtual machiines, containers, and much more.
MARS is used by 1&1 IONOS for geo-redundancy of thousands of LXC containers, and on several petabytes of data, with very low cost.
