We recently upgraded to Apache 2.4 and want to move away from the Prefork + mpm-itk setup we had in 2.2 . The problem is we host about 60 domains, and while we control the PHP development, we still want to have them isolated per domain, as over the years, we have had so many different developers, plugins, etc.
I understand we would have to create a FPM pool for every single domain, but how do we handle all the processes it will create? Does anyone have any suggestions on how they handle and limit this, while not causing stability issues.
