I would advise anyone setting it up to take the time and create the multiserver high availability model.
The software has modest backend requirements. It is extensible with many add-ons for getting applications like WordPress or Gallery up in running quickly. The high availability features have been working as expected with no downtime.
It’s open code, so you can change and customize your panel if you need it by your own extensions or third party, and its use it’s easier than other panels.
And the best maybe is its upgrade. It’s nos automatic, so you can create all of backups, snapshots and whatever you need for an safe upgrade.
Documentation on various setups is user contributed and at times may be slightly confusing – hint, read the comments to help get you through. There is a manual for the software but it doesn’t cover specific set ups, like on particular operating systems.
