An Energy-Efficient Strategy and Secure VM Placement Algorithm in Cloud Computing

Algorithm 1

Energy efficient VM algorithm (EEVMPA).

	Input: TS = {ts, ts2, …, tsn} ⟶ Tasks set,
	DLS = {dls1, dls2, …, dlsn} ⟶ Deadlines set,
	HS = {hs1, hs2, …, hsm} ⟶ Hosts set,
	VMts = {vm1, vm2, vm3, vm4} ⟶ VM-types set.
	VMsFree () ⟶ function to check the VM is free
	HostsFree() ⟶ function to check the VM is free
	Output: Energy consumed and makespan time
(1)	Update RQ ← SortedQueueTask (TS, DLS) from Algorithm 2
(2)	{Qs, Qt, Qu.} ← CategorizedTask (RQ) from Algorithm 3
(3)	for each and every task tkx ∈ TS then do
(4)	VMsFree () from Algorithm 4
(5)	HostsFree () from Algorithm 5
(6)	vm ← VMTypeSelection (tsx, VMType(tsx, TS)) from Algorithm 6
(7)	h ← HostSelection (vm) from Algorithm 7
(8)	Allot tsx to vm which is placed on host h
(9)	end for loop
(10)	VMsFree ()
(11)	HostsFree()
