As a user, Kitely's active regions act just like active regions on any other grid. It's not my fault that they found a cheaper way to do it than grids using an always-on architecture.
And there is no reason why other grids aren't taking advantage of on-demand cloud hosting, other than that it's difficult to set up.
It might not be fair to the grids with more expensive platforms, but that's life.
From a user perspective, the advantages of having always-on regions are small and shrinking all the time.
