Re: Microsoft .NET frontending IBM i

Then he might add a couple of cheap Windows servers on the front end to server up the web :-)

How will you handle if the system simply cannot handle more requests
per second?

I change the subsystem class for all the ODBC/JDBC database server
jobs to a time slice of 1 millisecond, and knock the run priority down
to 99, and allocate just 1 meg RAM to the subsystem. We only need
those jobs for serving .Net and JEE clients. It's fun to irritate
those people. That frees more resources for all our RPG CGI programs
;-)

Okay, if your box is pegged at 100% CPU utilization 24X7 and customers
begin complaining about performance, then you call IBM and order the
activation key for a capacity on demand upgrade. You enter the key,
and suddenly your server is running on 4 sockets instead of 2. CPU goes back down to 50%.

Ok, sounds very easy.

How expensive is such a "capacity on demand"-upgrade, and what do you do when you run out of these upgrades or they get too expensive?
