Discover how to implement simple long-distance replication with minimal effort in this 23-minute conference talk from linux.conf.au 2020. Learn about the new systemd interface of MARS and how it significantly reduces the complexity of making existing solutions geo-redundant. Explore the benefits of combining systemd with MARS's unit-file template generator for easier automation of handover and failover processes. Gain insights into the flexibility of this approach, supporting various application stacks including virtual machines and containers. Understand how 1&1 IONOS utilizes MARS for geo-redundancy of thousands of LXC containers across several petabytes of data at low cost.
