SLAs and provisioning
SLAs determine bounds on total response time = tserver + tcloud + tnetwork ≤ tthreshold so that
tserver ≤ tthreshold - tcloud - tnetwork = tmaximum. 
Thus, the goal of service switching is to insure that tminimum ≤tserver ≤tmaximum.
tminimum≤tserver for theoretical reasons. 
tserver≤tmaximum only if scale meets demand.
