> Task replacement and scaling primitives could allow easier up and down-scaling by reusing
resources from an old task either partially (leaving resource delta available), fully or augmented
(backed by additional offers) for launching a new task. Further, recovery logic can be applied
which restarts the old task in case of new task failure.
