[TYPO3-english] test and production on 1 VPS server

[Bas Heutink]

Hello list,

Is it necessary to test Typo3 sites on a completely different (VPS) 
server? Or is it okay to test Typo3 on the  same VPS server as the 
production environment? Of course the production websites have their own 
account in WebHostManager and the test website has also its own account 
in WebHostManager.

So the test website and the production websites have different databases 
etc... But they share the same mysql and apache server because they are 
on the same VPS server.

So the only thing is that production and test share the same 
mysql/apache server. Is this a risk? In other words can a Typo3 test 
site crash a complete myqsl/apache server? In that case there is a 
risk... Also in that case shared hosting is also in anyway inacceptable, 
because you then also share mysql/apache server with other clients, and 
these clients can let crash mysql/apache...

Regards,

Bas
