In researching Biztalk load balancing I have discovered that many people are
confusing it with high availability/clustering. I understand that I get high
availability merely by having more than one Biztalk server in the group.
However, in regard to load balancing, does Biztalk server handle spreading
the load automatically? For instance, If I have two production orchestration
servers named Biz1 and Biz2, and messages come in that require 10 different
orchestrations to run at one time, will 5 requests get pushed to Biz1 and 5
get pushed to Biz2? Thanks.

Yes, if you have two different servers running application host instances
then biztalk can certainly balance out message processing (notice that
depending on the rest of your configuration one server might get more work
than the other, so it won't always be 50/50).

There are some good comments (including some of mine) on this thread in
biztalkgurus on a similar topic:
