Energy-Efficient Resource Allocation and Migration in Private Cloud Data Centre

Algorithm 1

Resource allocation algorithm (overfilled and underfilled VM).

	Input: under-fullVMsList and overfilled VMsList
	Output: underfullVMsList
	Overfull VMsList
	UnderfullVMsList
	Underloaded VMs. sort. Private cloud data()
	for all LNP in overfull VMs file do
	LNP Overfull Hosts = overfull VMsList − 1
	LNP.VM.type calculation ()
	for all VM in overfull VMs List do
	for all LNP in underfullVMsList do
	LNP under-loaded Hosts = underfullVMsList − LNP
	if (underloadedVM.location == VM.location) then
	if (VM.size ≤ under-fullVM.size) then
	Add VM to underfullVMsList
	Place VM (under-loaded VM, VM)
	Insert standard file (under-loaded VM, VM.ID)
	end if
	else
	if ((VM.size ≤ under-fullVM.volume) && (under-full VMs. LNP. delay. minimum)) then
	set VM (under-full VM, VM)
	count standard file (under-full VM, VM.ID)
	end if
	if ((under-fullVMlist = 0) && (LNP.Overfull private cloud host = 0)) then
	end for
	Revisit underfullVMsList
