I’m looking for a guide on configuring one DHIS2 instance as a fail-over for another. Is this an easy(ish) thing to accomplish?
First prize would be a seamless failover without admin intervention.
Second prize would be for a live mirror server that can be quickly configured to take over as the primary server in an emergency situation.
We have two production instances of DHIS2 - one for aggregate data and one tracker instance. I’m thinking of a container based architecture that has both tracker and aggregate instance on the same physical box mirrored with a backup box of identical configuration that could take over in case of system failure.
