Compared
to the existing Bin Packing solutions, we creatively support item departure
which can effectively avoid the frequent placementchanges1 caused by repacking. Star
Student Project support green computing by adjusting
the placement of application instances adaptively and putting idle machines
into the standby mode. Experiments and simulations show that our algorithm is
highly efficient and scalable which can achieve high demand satisfaction ratio,
low placement change frequency, short request response time, and good energy
saving.
