However, T is dependent on the proper knowledge of therequired time for servers to switch from their initial SLEEP/ACTIVE state to the next desired state. The activitiesimplemented by this policy are (a) to relocate the VM from an encumbered server, a server that operates in anundesirably high regime with applications forecasted to rise their burdens to compute in the subsequent reallocationcycles; (b) to conduct VM migration from servers that operate within the undesirable regime to shift the server toa SLEEP mode; (c) putting an idle server to SLEEP mode and rebooting the servers from the SLEEP mode at highcluster loads. A novel mechanism for forwarding arriving client desires to the utmost suitable server is implemented;thus, in the complete system, balancing the requested load is possible
