SLA Aware Task-Scheduling Algorithm in Cloud Computing Using Whale Optimization Algorithm

Algorithm 1

Proposed task-scheduling algorithm using whale optimization.

	Input: set of tasks , set of VMs , set of hosts , Set of datacenters
	Output: Scheduling of tasks mapped to VMs while minimizing makespan, SLA Violation.
	Start
	Populate whale population randomly
	Calculation of priorities of using equation (5).
	Calculation of priorities of using equation (6).
	Calculation of fitness function using equation (11).
	if (probability < 0.5)
	if (|E| < 1)
	calculate search agent position using equation (13).
	else if (|E| < 1)
	calculate search agent position using equation (19).
	End if
	End if
	If (probability ≥ 0.5)
	Calculate position of search agent using equation (16).
	End if
	Calculate makespan, SLA violation using equations (7) and (10).
	If (agent moves outside region)
	Calculate
	Update iterations
	End if
	End
