Here is where I struggle. To me you are simply describing ways to
eventually get to the stability of the System i, whereas I didn't have
to
learn how to put together a server farm or understand complex hardware
configurations to make my 20 apps run on my i5 - I bought it and it
works.
All servers WILL GO DOWN. Period. They'll both go down for unexpected
reasons (software/hardware/environment) and for planned reasons
(software/hardware/environment upgrades). What I'm describing is a way
to provide application availability on a 24x7x365 manner at a fraction
of the cost of a single System i, let alone the minimum of two you'd
need to support 24x7x365.
