I want to have a Passbolt HA cluster and haven't found any information on how to build such cluster. Currently, I am thinking about two options. Maybe someone has experience with Passbolt HA and can suggest which one is viable or better?

Option 1: (https://imgur.com/t3wt9Om)

• MariaDB Galera Cluster
• The DB cluster has a virtual IP (keepalived VRRP).
• At least 2 app nodes (all nodes connected to the same DB VIP)
• HaProxy as a load balancer (one app node is active, other nodes are backup)

Option 2: This option is more simple, but I don't know if this option won't introduce some unexpected behavior (https://imgur.com/cN7gmDr)

• MariaDB Galera Cluster
• Passbolt application is also on the same server as the DB.
• No virtual IP (every app connected to its own DB, localhost DB)
• HaProxy as a load balancer (one server is active, other servers are backup)
