Relational-Data (www.relational-data.com) would have been happy to provide a
bid for an OS/400 based e-commerce application.

Do I understand correctly?  Add capacity by front-ending the iSeries
database server with a cluster of lower cost boxes?  Sounds like a page
right out of Microsoft's script!  Let me ask.  Is it more efficient for the
iSeries database server to build an ODBC or JDBC formatted stream, than to
build an HTML formatted stream?

In my testing, an AS/400 can serve dynamically generated HTML just about as
fast as it can serve ODBC data.  So adding an extra layer of hardware in
front of your iSeries is an unnecessary extra cost.  If your iSeries can't
handle an HTML load, it can't handle an ODBC or JDBC load either.

I'll tell you the real reason that IIS application providers recommend
clustered, load balanced IIS servers.  It's such an unstable platform to
host their applications that they use multiple servers to improve overall
uptime.  It's not a capacity issue.  OS/400 doesn't need failover support.
It's already stable.
