In this project, you are going to implement a security- aware task scheduling policy using the CloudSim toolkit. Your implementation should assume a heterogenous environment with the following specifications: 1. Each task (cloudlet) has a different performance requirement. 2. Each VM has a different processing capacity. 3. Each task has a set of security requirements, following the taxonomy defined in [1]. 4. Each VM has a set of security measures, following the taxonomy defined in [1]. 5. Assume a datacenter with two hosts, each with

SVM

.6. The taskset must contain 100 randomly generated tasks whose security requirements are randomly assigned. Your scheduling policy should work as follows: a. Each task must be assigned to a VM that supports all its security requirements. b. If there is no available VM that supports all of a particular task's security requirements, that tasks should be scheduled on a VM that supports no less than 60%

of its security requirements. - Simulate your

scheduling policy 50 times and report the following: Average task completion time. Security satisfaction ratio defined as the percentage of tasks scheduled on VMs that support at lean

751%

of their security requirements. Show the histogram of the task completion times and the security satisfaction ratio. Compare your results to a non-security-aware policy in which tasks are scheduled based on their processing demands only. [1] Al-Tarawneh, M.A.B.
