Final project: making the MasterLinux shop highly available

2 h Debian 12 Versions Debian 12, HAProxy 2.6, Keepalived 2.2, Pacemaker 2.1

Objective

Bring the whole course together on a complete case: the MasterLinux online shop currently runs on a single load balancer and a single database. You deliver an architecture with no single point of failure on the order path, configured, verifiable and documented, with a recovery plan the on-call team can follow. Allow 2 hours.
