Hi all

I have small doubt, how many instances we can create in production environment

and how many databases we can create on each instance

as per my knowledge we can create only one instance in production environment and also we can create multiple databases

if create multiple instances it will effect on performance on os level or system level

is this correct if anything wrong please correct it

Much of the information you need is here http://msdn.microsoft.com/en-gb/library/ms143432(v=sql.105).aspx. Although a lot of this would be dependant on if your hardware could cope with it.

Multiple instances will absolutely affect performance, yes. You just need to monitor your systems to understand how much they will affect it.
