I have the same question here.
And considering each Box is around 2GB is also something to take into account.
I first started grouping most of our sites in one installation, but the problem comes when they need to be deployed on a different server.
Currently I’m moving to a one installation per remote server, but Box size and configs are making me doubt if that is the best practice.
What is going to happen when having, let’s say, 50 different installations?
Some discussions were held around this: To deploy a second site
Can anyone share his experience?
