With my very breif understanding of load balance, if the web server are
implemented with load balanced then the database server Needs to be outside
of the load balance cluster group.
Is this correct?
Is it possible/easy to run clustered DB on the same web load balanced server
cluster group?

It depends on how the load balance device works. Some device dispatches all the
requests that belongs to the same session to the same machine, in this case
you don't need to do much. Otherwise there are many possibilities that the
application broke:
What if the application loads some data in application_start and somewhere
in the code the data is fetched from the cache without checking if it's null
or not?
How do you synchornized the data in the cache on different machine if you
need to?
What if

I think the company is trying to do with a single DB server and load
balanced web server cluster. cost for clustered SQL servers (liences) is too
high for now
There is no trick to deply to clustered servers right? A server company is
taking care of the physical servers, if I give them the web folder for
delopyment, I think they should know what to do.
