In this research, we pioneer a novel method to evaluate the maximum admissible load (MAL) for virtual machines (VMs) in physical machines (PMs) in data centre networks (DCNs), first in tree topologies and then in general topologies. This unique approach simplifies the issue into a problem with a linear solution in k-nary trees with constant k and into a single-source, multiple-sink max-imum flow problem in general topologies. It also resolves the maximum elastic scheduling problem by determining the optimal load for consistent growth without reassigning tasks. An effective strategy for these challenges is introduced and validated through testbed implementations and data-driven simulations.
