Let’s say I have to host 25 websites… How do I know how powerful should my VPS be? Which specs it should have, how fast the connection should be to handle X visits per day?
How do you understand which are your system requirements BEFORE deploying a project? Do you just make estimates and then scale up? Or there’s some kind of tool to benchmark? how to handle this kind of stuff?
I agree with everything said so far. Just wanna add that starting a little big and then shrinking resources can be less stressful if you value user experience more then some extra expense at launch.
