Hi everyone,

@Wise : I agree with you. There are several parameters that in the end determine the number of possible users. Since I mentioned the Pro Plan Cloud8 from UNA, I thought that UNA might have a recommendation for this.

@LeonidS : Thanks for the links. I did not know them yet. I will talk to our SysAdmin about the MySQL cluster.

We generally use individual boxes with a UNA installation on which the web server - Apache with PHP-FPM - and the database run. The systems are optimized and use Memcache, for example. Video conversion and streaming is not used much.

It is not possible to give an exact number of users here anyway. But perhaps you have some experience.
