CloudOrg Simulator

CloudOrg Simulator is a Cloud Simulation and analysis Project built using CloudSim Plus Library and Scala 3.0.2

This project is also designed to be a primitive CloudSimulation Framework. This project can help save significant overhead time in writing the code part. Users can just specify the Configuration files, and the redundant process of loading and running the simulation is taken care by this framework.

Project Overview

List of Simulations

1. Infrastructure as a Service (IAAS)
2. Platform as a Service (PAAS)
3. Software as a Service (SAAS)
4. Combination of IAAS, PAAS and SAAS in same Cloud Organization
5. Comparison of Different VM Allocation Policies (BestFit vs RoundRobin vs FirstFit vs Simple)
6. Comparison of Different Scheduling Policies (TimeShared vs SpaceShared vs (TimeShared + SpaceShared))

Implementation Details

Two parties are involved in the simulations

1. Cloud Organization (Org)
2. Client

Following factors are considered for this simulation project.

IAAS - Level of Control:

   Org: Host Configurations, Network Topology, Allocation Policies.

   Client: Select VMs, number of VMs, OS, Cloudlets to be deployed in the VMs, Cloudlet Scheduling Policies, etc.

PAAS - Level of Control:

   Org: Host Configurations, Network Topology, VMs Configurations, Allocation Policies.

   Client: Cloudlets to be deployed in the VMs, and number of Cloudlets

SAAS - Level of Control:

   Org: Host Configurations, Network Topology, Allocation Policies, VM Configurations, Cloudlet Configrations.

   Client: Number of Cloudlets, and which cloudlet the user is interested to use.
