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

Algorithm 7

Host selection.

	Input: VM-type,
	ACTH = {acth1, acth2, …, acthk} ⟶ Hosts which are in active state,
	SLPH = {slph1, slph2, …, slphk} ⟶ Hosts which are in sleep state.
	Output: Desired Host
	Algorithm: Host Selection
(1)	for each acthi ∈ ACTH then do
(2)	if VM of VM-type is able to fit in acthi then
(3)	Host ← acthi
(4)	Return Host then stop
(5)	end if loop
(6)	end for loop
(7)	for each slphi ∈ SLPH then do
(8)	if VM of VM-type is able to fit in slphi then,
(9)	Host ← slphi
(10)	Convert the state of slphi from sleep/non active state to active state
(11)	Return Host then stop
(12)	end if loop
(13)	end for loop
