in some cases, the price difference can be enough for you to have redundant
whitebox systems for the price of a single high-end system. this can seriously
alter the risk calculation (at the cost of double the space/power)
Agreed - Sometimes I recommend buying twice as many cheap boxes that cost half
as much, because if 10% of them are inoperable at any given time, you still
have 90% gain for the same cost.
That depends on whether your architecture requires a single high availability
machine to stay up all the time, or a cluster of disposable machines that only
some percentage of them need to be up at any given time.
the thing is, even if you need a box to be up all the time, your expensive
system is still going to go down sometimes. how will you deal with that?
Can that method then be used slightly more frequently to allow you to use the
cheaper systems?
