Please forgive my ignorance…
I have been piloting openfire/spark at my site for a couple of weeks and it has become popular (with about 20 users). Mgmt wants to roll this out to the enterprise (anywhere from 1000-2000) users.
We currently have an IM program that is planned for removal because of licensing and a retiring admin and we don’t have a good metrics regarding how much the current product is used.
What should be my concerns going from 20 users to 1000+ users and will the embedded database handle that load (or should I use mysql)?
