this in a redundant, load-balanced configuration for availability if not
scalability. That meant a minimum of two devices in the production
environment. But any medium-to-large organisation has a number of
environments in which its applications are deployed, i.e., development,
system testing, user acceptance testing (UAT), production and disaster
recovery (DR). We would have needed one device in the development
environment and two each in the others, bringing the total number of
devices to 9. A single device costing $100,000 really meant a cost outlay of
almost a million dollars for the overall solution.
So while the architectural model was quite elegant and the purchase was
well worth the price from an enterprise viewpoint, the usual budgetary
constraints ensured that this approach never got off the ground. You should
however consider this model if you can manage the initial outlay.
