Is this possible in Csla? fyi our data portal utilizes WCF as the protocol...

Sure you can, although it has nothing do with CSLA specifically.  You can load balance WCF Service, which is all you really need.

Exactly!

Just go get an HTTP load balancing appliance, or use some other HTTP load balancing technology.

I know there were issues load balancing Remoting, because it maintains a persistent TCP connection to improve performance. But with WCF I don't believe any persistent TCP connection is cached, so you should be able to use any HTTP load balancer.

Presumably this is also true of the Web Service portal?

I am currently using IIS7 and NLB (network load balancing) to accomplish this. IIS7 is easy to set up in  a web farm with because of the shared config feature. Windows Server 2008 has NLB built in so that is pretty easy to set up. We did have to dedicate a switch with a special configuration (Layer 2 Multicasting) to get it work correctly. Currently were hosting about 150 users across 3 data portal servers.

I would expect so, but recommend using WCF if at all possible.
