Multiple guacamole servers pointed at the same mariadb?

[Samuel Noble <sn...@nmcourts.gov>]

Hey all,
I'm standing up additional guacamole servers which should ideally stay in
sync (with respect to the connection and user lists)  to my current
production guacamole.
Can I just point multiple guacamole clients at the same DB or is that
something I should avoid?

There are two reasons why I believe people tend to ask about this:
- Scalability, so that they can scale out performance of Guacamole using
multiple servers/instances rather than constantly up-sizing a single server
or instance.
- High Availability, to guard against failure of a single
node/server/instance in the Guacamole environment.

I “accidentally” had just such a setup when I was attempting a vm backup of my Guacamole system – seeing this question makes me ask – Why exactly would you want to do this?  Does it help Guac in speed or stability?

Thanks

You can definitely do this. There should be no issue. Guacamole uses proper transactions where necessary.

Many thanks, I'd assumed and hoped that was the case!
